This paper, first brings out the formulae for calculating the base band weighted interferences noise power and the interference reduction factor of FM TV system, when the image interfered by digitally modulated signals is motionless.And then in accordance with the accurate algorithm given in Reference [1], it calculates the power spectrum of complex envelope of the pre-emphasized colour bar brightness signals, which are requisite for calculating the interference noise power. Since the algorithm proceeds from the wa'veform function of the colour bar brightness signals, no vedio spectral lines need be ignored so that the base band interference noise power of single frequency, PSK, ASK and FSK signals interference thus obtained is accurate and can be used to measure the accuracy of the approximate algorithm which takes into account only a few essential vedio spectral lines. In order to test the reliability of the calculated results, preliminary objective measurement is taken, the results of which coincide basically with the calculated results. Finally, on the basis of the calculated results, characteristics of interference from various digitally modulated signals, especially the digital-analog compatibility are analyzed, and some useful conclusions are drawn.

本文导出了调频电视系统静止图象受到数字调制信号干扰时的基带加权干扰噪声功率和干扰减少因子的计算公式,并参照文献[1]的精确计算方法,算出了计算干扰噪声功率需要的已预加重的彩条亮度信号的复包络功率谱。由于这种算法是从彩条亮度信号的波型函数出发,可不必忽略任何视频谱线,因而在此基础上得出的单频、PSK、ASK和FSK信号干扰时的基带干扰噪声功率是精确的,并可据以衡量只计入了主要视频谱线的近似算法的准确性。为了验证计算结果的可靠性,进行了初步的客观测量,结果与计算值基本吻合。最后,根据计算结果对不同数字调制信号干扰的特点,特别是数模兼容性进行了分析,并得出了一些有用的结论。
