Compression of signal samples output from a parallel, time-interleaved analog to digital converter (TIADC) (112) for a baseband signal (110), includes calculating (116) first or higher order differences of consecutive signal samples followed by lossless or lossy encoding (118) of the difference samples to produce compressed samples. Compression of a TIADC output signal (128) with a nonzero center frequency, includes calculating sums (124j) or differences (124j) of pairs of signal samples separated by an appropriate number of sampling intervals followed by lossless or lossy encoding (118). The sums or differences of the signal samples have lower magnitudes than the original samples, allowing more efficient compression.
