A VLSI chip set for ghost cancellation and waveform equalization of analog television signals

A VLSI digital filter chip set suitable for performing ghost cancellation and waveform equalization of analog TV signals is described. The complete chip set consists of one 72-tap and two 288-tap finite impulse response transversal filters. The devices, capable of operation at up to 15-MHz sampling rates, are appropriate for use with oversampled NTSC television signals. The three chip set (capable of performing 10 billion multiple-accumulate operations per second) provides full coverage for the Ghost Canceller Reference signal in Japan, and is also suitable for ghost cancellation in other countries as new reference signals are developed and broadcast
