发明名称 Television signal filtering system
摘要 A signal separation system is provided which includes a plurality of serially-coupled signal transfer stages. A video information signal is applied to an input stage and is delayed by at least the time interval of one horizontal television line (1-H) as it passes through the stages. Various ones of the stages which are 1-H apart in time include outputs, which are combined by weighting function and summing or difference circuits to produce bandwidth-limited transversal filter output signals. These signals are additively and subtractively combined to produce a combed band passed chrominance signal and a fully restored and combed luminance signal, thereby obviating the need for subsequent filtering before the signals are further processed. The bandwidth-limited signals may also be combined to provide a user adjustable peaking control signal for the luminance information channel.
