A switching circuit operable as an amplifier and a muting circuit. |
| 摘要 |
<p>A switching circuit for achieving the amplifying and muting operations is disclosed. The switching circuit operates as a non-inverting feedback amplifier whenever the circuit performs either amplification or muting. The non-inverting input port of the amplifier is always kept free to receive a given signal. An impedance element is connected to the output terminal of the circuit in either the amplifying or muting operation.</p> |
