Transversal filter capable of processing an input signal of high data rate

Abstract From the Canadian patent

In a transversal filter for filtering an input signal (IN) into an output signal (OUT) in response to first through third tap gains (C-1, C0 C1), the, transversal filter comprises a serial-parallel converter (40) for converting the input signal into first and second parallel converted signals. Connected to the serial-parallel converter, a delay circuit (10) has first through fourth taps (11-14) and comprises a plurality of delay units (16, 17) each of which is connected between two taps selected from the first through the fourth taps. Each of the delay units provides twice a unit delay which is substantially equal to a reciprocal of an input data rate of the input signal. The first through …
