In internally diplexed television transmitter,the nonlinear characteristic of amplifiers results in intermodulation distortion of three frequencies picture carrier frequency,color subcarrier frequency and aural carrier frequency.Intermodulation distortion is an important factor affecting the property of television transmitter.This paper discusses the origin of intermodulation distortion through mathematical analysis of nonlinear systems.The correction method and its achievement are described.The experimental results are given.

合放式电视发射机中,放大器非线性特性的存在,使得共同放大的图像载波、彩色副载波及伴音载波分量相互作用,产生这三个频率的合、差频失真,即互调失真。互调失真是影响电视发射机性能的一个重要因素。文中采用非线性系统的数学分析法论述互调失真产生的根源,阐述互调失真的校正方法及实现,并给出测试结果
