Abstract

PURPOSE: To realize the peaking for the high-band frequency in a simple way by providing the passive circuit comprising the inductor and capacitor to the emitter of the collector earth amplifier as well as to the input terminal of each video amplifier circuit.
CONSTITUTION: Collector-earthed video amplifier 3 receives the luminance signal which is processed and amplified through video amplifier circuit 2; and emitter- earthed video output amplifier 15, 25 and 35 receive each color difference signal processed and demodulated through color signal generator circuit. In case the luminance signal given from video amplifier 2 is supplied to the emitter of amplifier 15, 25 and 35 each, inductance element 6 is connected to the emitter of amplifier 3 and capacitor 7 is inserted between the other end of element 6 and the earth or the power source. Thus, the passive circuit consisting of the inductor and the capacitor is provided to the emitter of the collector-earthed video amplifier as well as to the input terminal of output circuit 15, 25 and 35 respectively, ensuring the peaking for the high-band frequency in a simple way.
