`ABSTRACT
`(57)
`Methods, Systems, and apparatuses for down-converting an
`electromagnetic (EM) signal by aliasing the EM signal are
`described herein. Briefly Stated, Such methods, Systems, and
`apparatuses operate by receiving an EM Signal and an
`aliasing signal having an aliasing rate. The EM signal is
`aliased according to the aliasing Signal to down-convert the
`EM Signal. The term aliasing, as used herein, refers to both
`down-converting an EM Signal by under-Sampling the EM
`Signal at an aliasing rate, and down-converting an EM Signal
`by transferring energy from the EM Signal at the aliasing
`rate. In an embodiment, the EM Signal is down-converted to
`an intermediate frequency (IF) signal. In another
`embodiment, the EM Signal is down-converted to a demodu
`lated baseband information Signal. In another embodiment,
`the EM signal is a frequency modulated (FM) signal, which
`is down-converted to a non-FM signal, Such as a phase
`modulated (PM) signal or an amplitude modulated (AM)
`Signal.
