Abstract
Abstract A transversal adaptive filter with a tap weight computer having a respective first and second input responsively coupled to a respective output and input of the filter, and including spectrum shaping means. The spectrum shaping means comprises matched or like preselected bandpass means interposed at the inputs of the tap weight computer.

Claim 5
Dependent Claim
15 words
The device of Claim 2 in which said spectrum-shaping filters are of like frequency response.
Claim 6
Dependent Claim
18 words
The device of Claim 4 in which said spectrum-shaping filters are like notch filters having a common bandwidth.
Claim 7
Dependent Claim
58 words
An adaptive sampled data filter comprising a transversal filter section in cooperation with a correlator-type tap weight computer as means for effecting spectrum-whitening of the spectrum of an applied signal input to said sampled data filter, and means in cooperation with said tap weight computer for preselective spectrum-shaping of the spectrum- whitened signal output of said adaptive filter.
Claim 8
Dependent Claim
58 words
An adaptive sampled data filter comprising a transversal filter section in cooperation with a correlator-type tap weight computer as means for effecting spectrum-whitening of the spectrum of an applied signal input to said sampled data filter, and means in cooperation with said tap weight computer for preselective spectrum-shaping of the spectrum- whitened signal output of said adaptive filter.
