Video waveform correctors for use with coaxial cable

Consideration is given to the problem of correcting for the effects of the attenuation/ and phase/frequency distortion of a coaxial-cable pair on the transmission of video waveforms. A method of designing correcting networks is described which uses an adjustable waveform corrector to provide the component values for a fixed network whose design tolerances are arranged to give the minimum waveform distortion. Using this method, the design of waveform correctors for use with coaxial cable becomes a rapid and straightforward operation.
