Methods of Measurement of Impulse Noise Susceptibility of TV Receiver

The usual method of determining impulse noise susceptibility is to feed various levels of noise from the motor in an electric shaver, electric eraser or electric drill to the antenna leads of a TV receiver and observe the effect upon the picture. The designer then attempts to determine what section of the TV receiver is being affected by the noise. This rather unknown level and type of noise is difficult to reproduce for comparison of various receiver designs. The method here proposed to test the receiver provides a known level of noise to test for horizontal and vertical sync stability, AGC set up, and white streaking.
