The effects of non-Gaussian noise on TV picture degradation are studied by using a composite noise generator(CNG) which can simulate the actual noise and control noise parameters such as power, APD, ACR, duration, and occurrence frequency. The disturbance is subjectively evaluated. The results show that the effect of noise power on TV picture is larger than those of APD and ACR, and the different MOS appears for cases of periodically and randomly occurred noise.
