Abstract

PURPOSE: To make it possible to extract efficiently a required video signal frequency band and also to reduce temperature drift, by using a low-pass filter in a processing circuit for a television video signal, etc.
CONSTITUTION: A signal inputted from terminal 13 is amplified by transistor 1 and the low-pass filter composed of resistances 7 and 8 and capacitor 9 removes a component of an unneeded frequency band; and 1st emitter follower transistor 2 performs impedance conversion and 2nd emitter follower transistor 3 or 4 lower the impedance again, thereby extracting an output.
