Patent ID: 8086197

Claim:
A multi-channel receiver comprising: an analog-to-digital converter (ADC) configured to convert using a sampling rate S an analog signal z which resides in a frequency band B Hz to a digital signal x, wherein digital signal x is representative of analog signal z; and a multi-band selector circuit configured to receive the digital signal x and to map the digital signal x into M time domain sub-signals x 1 . . . x M , wherein each sub-signal represents in a time domain a frequency domain content of digital signal x, wherein each sub-signal resides in a sub-range of band B, wherein each frequency component of digital signal x is represented at least in one of the sub-signals x 1 . . . x M in its original form, and wherein each of the sub-signals x 1 . . . x M has a sampling rate less than S, and the sub-ranges overlap.
