发明名称 Automatic gain control circuit for burst signal communication system
摘要 An AGC circuit for amplifying burst signals has output power which does not vary, regardless of variations in the burst time. This automatic gain control (AGC) circuit has an amplifier for receiving a burst signal input and providing an amplified burst output. The level of amplification is controlled in response to a control signal applied to the amplifier. A negative feedback circuit includes an envelope detector for receiving the burst output and a circuit for providing a comparison signal in response to a comparison between the voltage leads of the detected envelope signal and a reference voltage. The comparison signal is converted into a binary signal which is counted down to provide the amplifier control signal.
