  • Incremental AGC signal generator with controllable increments
    Patent number: 4075573
    Abstract: A comparator is connected to the output of a variable gain amplifier and, when the output signal exceeds a predetermined threshold, pulses are applied to a plural stage shift register in series, with incremental voltages being generated in parallel at the outputs of the various stages. The incremental voltages are applied to the amplifier to vary the amplification thereof, and a threshold detector and timer also sense the output of the amplifier and reset the shift register when the output of the amplifier is below a predetermined value for at least preset period of time. One or more additional comparators may be included in the circuit to cause the shift register to activate one or more of the higher stages directly when the output of the amplifier exceeds a second predetermined amplitude. A step control circuit for shaping the response curve of the amplifier is also included.
