Patent ID: 8401050

Claim:
Receive path circuitry for a sampling receiver having folded Nyquist zones, comprising: multiple sampling clocks that are each configured to produce a respective sampling clock signal, at least one of the multiple sampling clocks being a modulated sampling clock configured to produce a modulated sampling clock signal that has a center frequency that is different from the center frequency of a sampling clock signal produced by at least one other of the multiple sampling clocks; sampling circuitry having a sampling circuit input configured to receive input signals within a bandwidth wide enough to cover multiple Nyquist zones associated with the modulated sampling clock, the sampling circuitry configured to receive the input signals and to receive each of the sampling clock signals from the multiple sampling clocks, each of the sampling clock signals being configured to provide sampling for the input signals within the multiple Nyquist zones to produce a separate and different image corresponding to each input signal, and the modulated sampling clock signal being configured to provide non-uniform sampling for signals within the multiple Nyquist zones to induce frequency modulation on signals dependent on a Nyquist zone of origin; and a sampling circuitry output configured to produce a sampling circuitry output signal that includes the multiple different images generated by sampling each input signal using each of the multiple sampling clock signals, the multiple different images including at least one first image and at least one second image corresponding to each input signal.
