| Research Abstract |
Disturbance from electrical equipment influences to TV broadcasting system, and the disturbance level is controlled in each country. The limit is determined from the study about analogue TV broadcasting. Therefore, we should study whether the limit is appropriate to the digital TV. In this study, the influence to both the digital TV and the analog TV was investigated to study the evaluation method of the disturbances. The study showed that the evaluation by the average power or the APD is appropriate compared with the quasi peak value which is used to evaluation of the disturbance level.
