Degaussing Circuits for Color Television Receivers

In 1967 the PTC resistor was introduced to the American TV industry for color television degaussing. This new component caused comparisons of performance and economics to be made with existing techniques. The PTC degausser offered sufficient advantages so that by 1971 it was used in 50% of color televisions made in this country. After a general review of degaussing this paper explains the circuitry, advantages, anddisa disadvantages of various degaussing techniques.
