Abstract

PURPOSE: To reduce the color fading on the screen as well as to prevent occurrence of the ringing distortion caused by the transient response waveform by combining the band pass type secondary differential circuit using the active element with the nonlinear element application type noise reducing circuit.
CONSTITUTION: The color signal process circuit is inserted into the input or output side of the band amplifier circuit of the color signal process system for the color TV picture receiver or the like. The process circuit is then composed of serial resonance impedance Zc connected between the collector of the amplifying transistor Tr and power source VCC and serial resonance impedance Z1 connected between the emitter and output terminal 7. Furthermore, resistance RE is connected between the emitter and the earth, resistance R2 is connected between the collector and terminal 7, and input terminal 6 is connected to the basse of Tr5. Otherwise, color noise eliminating diode D1 and D2 are connected between the collector and VCC, and color noise eliminating resistance R4 is connected between th earth and the junction of diode D1 and D2. Thus, the color signal process circuit is obtained.
