TRANSISTOR RADIO RECEIVER EMPLOYING AN IMPROVED SQUELCH CIRCUIT

In a transistor radio receiver, two time constant resistors, one of which is a variable resistor, are connected in series via a signal detection circuit to a power source and a time constant capacitor is connected to the junction point of the two resistors to form therewith an automatic gain control voltage generating circuit, and a squelch transistor whose base is connected to the movable terminal of a potentiometer, so that the squelch transistor which is normally biased to be conductive is quickly cut-off in response to even a weak signal input to the receiver.
