摘要
本文采用切比雪夫函数分析方法分析了环形振幅调制器。并用计算机计算了调制系数,非线性失真系数,调制信号的波形失真,所得计算值与测量值结果一致,并得出调制信号的振幅、直流偏置电压的取值范围。本文还介绍了单平衡调制器和中频调制器以及工艺设计要求。
In this essay, Tchehycheff Function is employed to analyse the amplitude modulators. The modulation factor, non-linear distortion factors, and the waveform distortions of modulation signals are computed. The calculated values are found to coincide with the measured. The range of amplitudes of modulation signals and of direct current bias to be taken are obtained. Single-balanced modulator and intermediate modulator are suggested and the requirements in the technical design are introduced.
