Patent ID: 7893852

Claim:
A method, comprising: converting an analog signal to a sequence of sets of signal samples using a plurality of parallel, time-interleaved analog to digital converters that are configured to form sets of samples of the analog signal during respective clock intervals and to output corresponding sets of signal samples at a clock rate that is the inverse of the clock interval, wherein a nth signal sample is output from a nth analog to digital converter, where a plurality of signal samples in each set represents consecutive samples separated in time by a sampling interval that is less than the clock interval; adding or subtracting a plurality of corresponding offset signal samples to or from the plurality of signal samples in a particular set in the sequence of sets to form a plurality of modified samples, wherein each corresponding offset signal sample is separated in time from a corresponding one of the plurality of signal samples in the particular set by a predetermined number of sampling intervals; encoding the plurality of modified samples to form a plurality of compressed samples at a bit rate in response to one or more control parameters; measuring a compression result parameter of the compressed samples; comparing the compression result parameter to a desired compression parameter to form a comparison parameter; and adjusting at least one of the control parameters in accordance with the comparison parameter to modify a bit rate of the compressed samples.
