    We have newly developed a programmable composite noise generator(P-CNG) which can easily control noise parameters such as average power, time-based amplitude probability distribution (APD), average zero crossing rate, occurrence frequency distribution and burst duration. A composite noise is made by the combination of some Gaussian noises, each of which has different amplitude RMS and duration. Using the P-CNG, the influence of composite noise on TV picture degradation is evaluated by opinion tests. Five simple composite noise models with some kinds of APD are used, in which value of other parameters such as average power is constant. The experimental results show that the envelope and APD of composite noises do not largely influence to mean opinion scores.
