Abstract:
1. A signal processing system comprising: (a) a multi-channel subsystem for converting a set of analog input signals into an unequalized, digitized complete-channel output signal which includes a plurality of sub-channels, and (b) an equalization subsystem for calibrating the unequalized, digitized complete-channel output signal to yield an equalized, digitized complete-channel output signal, (c) wherein the equalization subsystem comprises a multi-channel corrector for calibrating the individual sub-channels of the unequalized, digitized complete-channel output signal relative to one another, the multi-channel corrector comprising a plurality of filters, each of the plurality of filters being assigned to calibrate a corresponding sub-channel using all sub-channel data from the unequalized, digitized complete-channel output signal.
