  • Complementary pre-emphasis and de-emphasis circuits for a video signal transfer channel
    Patent number: 4281346
    Abstract: Complementary circuits for pre-emphasis and de-emphasis of video luminance signals, the circuits permitting an improved signal-to-noise ratio in a video signal transfer channel. The video signal has separate frequency- and amplitude-sensitive portions as well as a linear gain portion, thereby providing a fixed gain up to a predetermined lower frequency, a fixed response between this frequency and a variable upper frequency breakpoint, and an amplitude-dependent gain above the upper frequency breakpoint. De-emphasis is performed by a circuit also having separate frequency- and amplitude-sensitive portions and a linear gain portion, and which may be readily matched to the pre-emphasis circuit.
    Type: Grant
