Title: Muting circuit
Inventor: TSUN KENZOU
IPC: H04B1/10
Filed: 1983-08-12
Abstract: PURPOSE:To obtain a muting circuit where a transient noise is eliminated completely by utilizing effectively a capacitor connected to a bias point of an output amplifier. CONSTITUTION:When a power is applied, a potential +V is increased gradually and a transistor (TR) Q4 is turned on accordingly. Then a charging current flows to a capacitor C2 through a diode d4, the TRQ4 and a resistor R4. The potential at a point A is increased by the charging of the capacitor C2. When the charging of the capacitor C2 is progressed and the potential at the point A reaches 1/2VF, a TRQ4 is turned off, resulting that TRs Q5-Q7 are turned off. Thus, a constant current from the constant current source flows to a TRQ3 so as to release the drive blocking of a differential amplifier 12. In taking a time constant comprising the resistor R4 and the capacitor C2 larger than the period when the transient noise due to application of power supply in the curcuit is caused, since the drive of the amplifier 12 is blocked completely while the transient noise is generated and relinquished, no noise is outputted.
