Patent

CA 1199588

A B S T R A C T A signal conditioning system is disclosed for modifying the dynamic range of an electrical. input signal. The system comprises a gain control circuit for controlling the gain of the input signal as a function of a gain control signal, and a control signal generating circuit for providing the gain control signal. The control signal generating circuit compri- ses a section generating a first signal as a function of the amplitude of the input signal, and a section responsive to the first signal for generating the gain control signal as a function of only those portions of one polarity of the time derivative of the first signal. Circuits are provided for substantially lengthening and/or linearizing the release behavior of the control signal waveform applied as the con- trol signal input signal to the gain control circuit and circuits are provided for adjustably shaping the release be- havior of the control signal input signal to the gain control circuit.
