Abstract
PURPOSE: To prevent both the occurrence of signal distortion and the noise overlap, by dividing the input buffer into plural systems in a stereo demodulator circuit and at the same time using a combination of the NPN and PNP transistors.
CONSTITUTION: The input signal supplied through the terminal 3 is delivered to the terminal 5 via the NPN transistor TR20 and PNPTR21 as well as to the terminal 4 via TR20 and PNPTR22 each. As a result, the occurrence of signal distortion due to the next-stage circuit to be connected to the terminal 5 can be prevented. At the same time, the noise of the next-stage circuit is never inducted to the terminal 4. Furthermore the strain caused by the single TR can be reduced.
