  • Patent number: 4646152
    Abstract: Circuitry for enhancing the sharpness of bandwidth compressed television signals provides equalization in only the transmitter with no equalization required in the receiver. The transmitter includes a linear phase delay and edge peaking circuit, a low pass filter and an equalization circuit. The linear phase delay and edge peaking circuit includes a tapped delay line which provides weighted output signals for differential phase delays. The weighted output signals of the tapped delay line are differentially combined to provide a combined output signal. This combined output signal and a signal from the tapped delay line are supplied to a peaking circuit. A clamping circuit is connected to limit the amplitude of high level signals in the combined output signal so that small transitions are peaked to a greater degree than large transitions.
