Abstract

PURPOSE:To form circuits on one chip of an IC, by constituting two filters, which separate a luminance signal and a chroma signal, with transversal filters using signal charge transfer elements. CONSTITUTION:The signal from the trap circuit supplied to input terminal is supplied to the series circuit of delay circuits D1-D10 constituting a charge transfer element such as a BBD. Outputs of circuits D2, D4, D6 and D8 are supplied to synthesizer A1 through weighting circuits X4, X7, X11 and X16 to separate the luminance signal. Outputs of circuits D1-D10 and the input signal are supplied to synthesizer A2 through weighting circuits X2, X3, X6, X8, X9, X12, X14, X15, X18, X20 and X0 to separate the chroma signal. As a result, all circuits are formed on one chip of the IC, and the number of parts is reduced, and the man-hour for assembling and adjustment is reduced.
