| 内容記述 | Spread Spectrum Clocking (SSC) is used for many PCs to satisfy a regulation of emission. The SSC affects to the wideband radio communication system, such as wireless LANs, compared with the narrow band radio communication system because SSC has a wide band spectrum. In this paper, the influence of SSC to the digital TV signal was compared with the influence to the analogue TV signal. A frequency modulation (FM) signal was used instead of the SSC signal. And these signals were impressed to both the analogue and the digital TV signal simultaneously. The received image quality was evaluated by the mean opinion score (MOS). The ratio of the disturbance to the broadcast signal level (DU ratio) was used as the parameter. The quasi peak level was used to calculate the DU ratio. The results indicated that the difference of DU ratio, when FM and AM signal were impressed to the TV signals, was small in the case of analogue TV, but the deviation of DU ratio is about 15 dB in the case of a digital TV. The results also show that the DU ratio of the digital TV was 20 dB lower than that of the analogue TV when MOS was 3. | |||||
