  • FM composite signal processor
    Patent number: 5913152
    Abstract: A signal processor for amplitude and frequency limiting of a multiplex FM composite signal is described. To maximize the amount of available bandwidth and minimize the generated distortion, the disclosed signal processor employs multiple low-distortion amplifying and clipping subsystems. The subsystems include a stereophonic pilot signal protection circuit which protects the 19 khz pilot signal from the composite FM signal processing, an adjustable limiting circuit, and an adjustable dual low-pass filter/overshoot compensation circuit.
