1、中国电视频道频率划分表注：下表提供的是图像载频频率。中国电视是PALD/K制式，图像信号带宽7.25MHz，伴音载频比图像载频高6.5MHz，带宽±0.25MHz,所以每个频道带宽为8MHz，从图像载频-1.25MHz至图像载频频率+6.5MHz。例如，3频道的图像载频频率是65.75MHz，由此可推算出其伴音载频频率是72.25MHz，频率范围是64.5-72.5MHz。场频25Hz，行频15625Hz。开路电视闭路电视频率参数波段频道国际编号国内编号频率范围图像载频(MHz)伴音载频(MHz)I波段(米波)DS—11148.5-56.549.7556.25DS—22256.5-64.557
