Abstract
An examination of the dimension of television picture noise attributable to videotape is presented. An improved measuring technique for correlating visual impairment is offered, which differs from the traditional technique in the use of a 100-kHz to 1-MHz band-pass filter in place of the 0- to 4.2-MHz filter. The measurement is made with the recorder demodulator gain set for 1-V peak-to-peak composite video output. On playback of an unmodulated grey-level carrier signal, the signal at the output of the demodulator was routed through this band-pass filter and the noise read directly on a wideband rms voltmeter.
