Two New Waveform Generators for Television Testing

A brief description is given of the test waveforms currently used in television testing. The division of the possible waveform distortions into two distinct types led to the decision to design two separate test waveform generators, a sine-squared pulse and bar generator for linear waveform distortion measurements and a gray-scale generator to measure nonlinearity. A brief overall description is given of these two units together with a more detailed explanation of some of the more important parts of the circuits. Finally, a brief description is given of the measurements which may be carried out on both monochrome and color television systems using these two units.
