1030 Exhibit: Second Declaration of John Villasenor

Document IPR2018-00643, No. 1030-35 Exhibit - Second Declaration of John Villasenor (P.T.A.B. Mar. 22, 2019)
Tektronix appears to support its construction based on the following statement in the ’719 Patent—“[t]he ’719 patent describes that via the selector 53, ‘circuitry that can be optimized for analysis in the frequency domain, such as the downconverter 57 …, can be added to a single channel.’” POR, 13; Case IPR2018-00643 Attorney Docket No: 44276-0002IP1 Ex.1001, 7:3-6.
Accordingly, this disclosure in the ’719 Patent is clear evidence to me that Tektronix and Dr. Blalock have no basis (even intrinsically) for their assertion that a time domain channel cannot include circuitry for removing or distorting frequency components of a signal.
The “[p]rocessor 520 reads this information and determines the estimate of the noise level of the channel based on a percentage of the symbol periods that the output of filter 510 exceeded or fell below a set threshold.”
For instance, the processor 520 would have to include a memory in order to determine the percentage of the symbol periods that the output of filter 510 exceeded or fell below a set threshold and the estimated noise level.

2023 Exhibit: Villasenor Deposition Transcript dated 4 12 19

Document IPR2018-00647, No. 2023 Exhibit - Villasenor Deposition Transcript dated 4 12 19 (P.T.A.B. Apr. 29, 2019)
"Figure one depicts in block diagram form a digital storage oscilloscope 10 of the present invention adapted to digitize an analog of input signal V sub T to store a compact data sequence representation of a selective frequency band of the V sub N signal, and subsequently to produce time and frequency domain displays of the band according to the story data sequence."
If the board determines that a channel as claimed in the '719 patent ends at acquisition memory, do you agree that Hansen does not disclose a two-channel test of measurement instrument?
Looking at column three, line 42, where it begins, "Figure one depicts in block diagram form a digital storage oscilloscope 10 of the present invention."
So in preparing your analysis, did you do any research as to what a person of ordinary skill in the art would understand to be the meaning of acquisition in the context of digital storage oscilloscope when you're analyzing the Hansen reference as to any invalidity issues for the '719 patent?
Q. I'm asking whether you did any research as to what a person of ordinary skill in the art would understand as to the meaning of acquisition in the context of a digital storage oscilloscope that is referred to in Hansen when you were preparing your analysis?

1032 Exhibit: US Patent No 7,860,674 to Freidhof et al

Document IPR2018-00647, No. 1032 Exhibit - US Patent No 7,860,674 to Freidhof et al (P.T.A.B. Mar. 22, 2019)
The fact that phase and respectively timeerrors in the two paths of the measured signal—analog-digital converter or triggering system—are mutually superposed and under extreme conditions can bring about a doubling ofthe effect can be seen as an additional disadvantage.
In this manner, an occurring triggering offset can be minimized corresponding to the numberof selected, additional, sampled values of the reference signal, which are calculated by meansofinterpola- tion—preferably by means of polyphasefilter.
In this context, a technically-meaningful compromise must be found betweenthe realized accuracy in determining the triggering time and the numerical cost of calculating the additional sampled values S;' of the reference signal S, by meansofinterpolation.
Following this, in procedural stage S120, the additional sampled valueS,,,,' of the reference signal S, in the middle ofthe timeinterval observedin iterative step j+1 is determined by interpolation.
While the invention has been described in connection with a number of embodiments and implementations, the inven- tion is not so limited but covers various obvious modifications and equivalent arrangements, which fall within the purview ofthe appended claims.

1033 Exhibit: US Patent No 6,310,566 to McNeely

Document IPR2018-00647, No. 1033 Exhibit - US Patent No 6,310,566 to McNeely (P.T.A.B. Mar. 22, 2019)
Known, classical interpolator configurations have been thought to be optimal in terms of maximizing performance and minimizing the hardware complexity involved,1.e., the numbers of adders, multipliers, registers etc. that are used.
However, the sample rate converter, interpolator and digital filter systems and the methodsoftheir derivation presented herein provide improvements over the knownfilter designs in both performance and reduced complexity.
FIG. 4 showsa table indicating coefficient values and the effective filter delay in conjunction with the corresponding position index signal for the reduced complexity digitalfilter of unit 40 of FIG. 3.
Important objectives in sample rate converter design are: 1) maximizing performance including minimizing alias (i.e. interference) components in the Pass Band, and 2) minimiz- ing complexity (e.g. measured in the number of adders required for an implementation).
a sequence of cascaded interpolators, an advantageous sample rate converter configuration is derived offering reduced complexity and improved performance overprevi- ously deemed optimal arrangements.

1030 Exhibit: Second Declaration of John Villasenor

Tektronix appears to support its construction based on the following statement in the ’719 Patent—“[t]he ’719 patent describes that via the selector 53, ‘circuitry that can be optimized for analysis in the frequency domain, such as the downconverter 57 …, can be added to a single channel.’” POR, 12; R&S- 1001, 7:3-6.
Accordingly, this disclosure in the ’719 Patent is clear evidence to me that Tektronix and Dr. Blalock have no basis (even intrinsically) for their assertion that a time domain channel cannot include circuitry for removing or distorting frequency components of a signal.
Indeed, if Tektronix’s characterization that the conventional oscilloscope performs the operations of receiving, conditioning, acquiring, and “post-acquisition” processing were to be adopted, even the test and measurement instrument claimed by the ’719 Patent possesses these characteristics.
As I had noted earlier in ¶¶[65]-[67], a POSITA would have readily appreciated that lines drawn across Hansen’s FIG. 2 (signal flow diagram) Case IPR2018-00647 Attorney Docket No: 44276-0002IP2 correspond to different paths implemented in Hansen’s system shown in FIG. 1.
Tektronix argues that Petitioner fails to satisfy its burden of obviousness of Case IPR2018-00647 Attorney Docket No: 44276-0002IP2 claim 7 by allegedly going beyond the disclosure of Hansen and relying solely on my declaration for support.

These three components are expen- formed to generate thousandsof sets of required polyphase sive and consumea large amount of power, if designed for filter coefficients in real time, expends significant computa- minimum signal degradation.
Real- SRCsystemsfor filter coefficients alone, in addition to their time, all-digital SRC systems are becoming more and more computational complexities falling in the neighborhood of significant because digital processing of signals, such as 10 MIPs for one channel of high quality audio.
As an initial matter in that regard, only FIR filters are utilized in the embodiments disclosed herein, because they offer linear phase responses andeffi- cient polyphase implementations in multirate processing.
FIG. 7 is a block diagram of the SRC filter 140 of FIG. 6 expanded in detail to assist in understanding the selection process back through the stages, as explained above in connection with FIG. 5.

Circuit noise, however, is random, caused for example by fluctuations in electrical power sources, atmospheric distur- bances (such as lightening, physical shock, high energy radiation particles), or other unpredictable events.
The GRAYCHIP™GC4114 Quad Transmit chip is the first ver- sion of this product to include an embodiment of the invention and will be commercially available from GRAY- CHIPInc., 2185 Park Boulevard, Palo Alto, Calif. 94306, the assignee of this patent application.
As illustrated in FIG. 1, digital transmit circuit 100 is partitioned into two identical segments 136, 138, which respectively process the complex sample components (real (Q) and imaginary (D) of a signal.
Accordingly, exclusive-OR gate 600 asserts autore- set signal 222 when an overflow is detected, thereby auto- matically and promptly recovering CIC interpolation filter 104 without requiring system level intervention.
The communication system in this embodi- mentinitializes storage register 702, over data bus 708, with a predetermined threshold governed by A(R“~), where A is the maximum amplitude (magnitude) of the input samples to CIC interpolation filter 104.

A. I think it's -- I've been -- The first time I was retained for a patent matter, I believe, was in the mid-1990s, and so that was over 20 years ago, and I've done work on various cases since then, so it's a decent number, but I haven't kept a tally, so I don't recall.
I do know that the decision at the end was made to move forward with Engelse and Hansen, so that suggests that that was the art that was -- was deemed the most relevant and on point, but I don't remember the specifics, because it was -- I think it was almost two years ago.
Now, in this sentence it indicates "two years of experience in performing time and frequency analysis of signals such that the person would have grasped sufficient details regarding the design and operation of test and measurement systems."
So starting on paragraph 40 of the -- Engelse Declaration, I have a construction of time aligned with the important qualification that that's relevance -- in relation to the claims, and so I -- I wasn't attempting to construe the term in the background.
And so, turning back to the background section, and in particular line 33, when it indicates that "Such measuring instruments," and this is referring to having a -- oscilloscope and spectrum analyzer, that they're not time aligned, what does that mean to you?

I have written widely in the field of electrical engineering, including several editions of a textbook that is used across the world to teach principles of microelectronic circuit design to undergraduate and graduate students.
The test and measurement instruments disclosed in the ’719 patent includes an input channel similar to the one found in conventional oscilloscopes for enabling time domain analysis.
Thus, the circuitry in the time domain channel is selected and configured to maintain the full bandwidth, to the extent possible, so that the acquisition system can capture all frequency components of the input signal accurately for display in the waveform.
Engelse explains “[i]ntegrating the spectrum analysis function enables quick reaction to changes in noise on a communication medium to reduce negative impacts on the transport of data over the medium.” Ex. 1007, ¶29.
Engelse explains that this threshold value is established based on factors such as the type of modulation to be used to carry signals over the monitored frequency band or channel, expected power levels, and the like.
