Matrixschaltung für eine FM-Stereo-Multiplexdemodulationsschaltung

摘要

A matrix circuit includes a first resistor (RA) having one end connected to receive a current signal and another end connected to a first output node (51), a second resistor (RB) having one end connected to the one end of said first resistor (RA), a first bipolar transistor (Q3) having a first collector connected to the another end of said second resistor (RB), a first emitter connected to a circuit ground (GND) and a first base connected to said first collector, and a second bipolar transistor (Q4) having a second collector connected to a second output node (52), a second emitter connected to said circuit ground (GND) and a second base connected to said first base.
