摘要
本文详细地分析了放大器非线性失真的主要参数——交扰调制比,二阶、三阶载波互调比的物理意义和计算公式,并由此推导出电缆电视系统的设计方法。另外,本文还讨论了西德DIN45004测试法。
This paper presents a detailed analysis to the physical meaning and calculation formula for the main parameters of nonlinear distortions in amplifier: cross modulation ratio, 2nd order cross modulation ration and 3rd order cross modulation ratio. In addition, the paper also presents a discussion on the measurement method given in German standard DIN 45004.
