Abstract:
An apparatus for providing control for a signal processor having a plurality of taps, with each tap having a tap value signal, comprising:a modulator for modulating each of said tap value signals with an attenuated unique code such that the amplitude of said code is less than said tap value signal to generate a modulated tap value signal;a summer for summing each of said modulated tap value signals to generate an aggregate tap value signal;a match filter, responsive to said aggregate tap value signal, for distinguishing said tap values from each other utilizing said unique code set for each tap value;a demodulator for demodulating said filtered tap value signal to generate a demodulated tap value signal; andmeans for adding said demodulated tap value signal to said tap value for each tap, thereby providing servo loop control for said tap.
