摘要: A television signal is distorted by passing it through a distortion amplifier which applies Gaussian curve to the signal. The has maximum increase in amplitude of about 38 dB, 30 dB with respect video carrier. further modified addition gated jamming signals between and audio carriers. are present only during horizontal vertical blanking intervals so do not affect quality picture reproduced receiver. restored applying filter function inverse function. removed restoring degree permits receiver read sync color burst intervals.
