`
`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.
