NE-139-MK (048A/M3) "Circuit for Cancelling Whole or Part of a Waveform Using Nonrecursive and Recursive Filters" ABSTRACT OF THE DISCLOSURE The whole or part of a waveform is cancelled by a circuit comprising a nonrecursive filter and a recursive filter. The nonrecursive filter has a plurality of first multipliers having first tap weights for modifying symbols successively shifted along a shift register. The recursive filter is connected in a series circuit to the shift register and has a second tap weight for recursively modifying the output of the shift register. The recursively modified symbol is modified by a second multiplier having a third tap weight and combined in an adder with the symbols modified by the first tap weights to produce a replica of an undesired waveform. The replica is destructively combined in a subtractor with an incoming symbol having an undesired waveform. The output of subtractor is utilized to derive the tap weights to adaptively control the inputs to the adder.
