Interference to Color and Monochrome Television Receivers by Oscillator Radiation and Other CW Signals

The concept and the measurement of the Beat Size Effect in television are discussed. It is shown that as a result of this effect, a monochrome signal may tolerate interference 25 to 30 db stronger when the interference falls in the upper part of the channel as compared to the level which may be tolerated near the picture carrier. NTSC color television does not enjoy this advantage.
