A SYSTEM FOR MEASURING THE QUADRATIC CONTENT OF TELEVISION SIGNALS,

Abstract

A system is devised for the measurement of the quadratic content of television signals. A unique feature of the system is that the video signal from the television system is connected directly to an oscilloscope and the measurement taken from the CRT using an optical mask technique. In addition to the measurement of quadratic content and r.m.s. valves, the system can measure other properties of the signal if the appropriate mask is substituted for the square law mask. The construction of the system is simple, requiring commercially available instruments and only a few electronic circuits. Accuracy of quadratic content measurement is approximately =20%, and =10% for r.m.s. and signal-to-noise measurements.
