| Zusammenfassung: | The proposed sound automaton contains a microphone, a control unit with logic elements, an output amplifier with two transistors, an isolating transformer, which is inserted in the emitter circuit of the bipolar transistor of the amplifier, and a diode bridge rectifier, which is connected to the secondary winding of the transformer. The positive terminal of the rectifier is connected to the gate of the power field-effect transistor of the amplifier. |
