Modification of the Pulse-and-Bar Test Signal with Special Reference to Application in Color Television
It is proposed to modify the pulse-and-bar test signal, which has been used in England to measure linear waveform distortion in TV systems, by a special 20T sine-squared pulse. This pulse is formed by the linear addition of a 20T-pulse to the pulse modulated on the color subcarrier. Transmission distortions can thus be recognized at the upper end of the video band. The deformation of the envelope of such a pulse indicates various transmission distortions of the luminance and chrominance channels. The combination of this 20T-pulse with the elements of the existing pulse-and-bar test signal is also suggested.
