Abstract:
1. An automatic gain controller, comprising: a first multiplexer for receiving an input signal and a gain and generating a first output; a second multiplexer for receiving a signal time constant and a gain time constant and generating a second output; a filter electrically connected to said first multiplexer and said second multiplexer, and generating a signal energy when said signal time constant modulates said input signal and generating an actual gain when said gain time constant modulates said gain in response to said first output and said second output; a signal-energy processing device electrically connected to said filter, said first multiplexer and said second multiplexer for generating said gain and said gain time constant in response to said signal-energy; and a multiplier electrically connected to said filter for multiplying said actual gain by said input signal to generate an output signal.
