相乘器在频率变换技术中的应用

The Application of Multiplier in Frequency Transformation

频率变换是无线电通信系统中不可缺少的过程,频率变换是由非线性元件及其组成的电路来实现。相乘器是由非线性元件组成,可以实现两个信号的相乘,完成频率变换的电路。该文从原理上分析了相乘器在频率变换中的应用及过程。

Frequency transformation is an indispensable procedure in the communication system of radio, which is realized by nonlinear elements or the circuits of nonlinear elements; Multiplier is the circuit which is conformed of nonlinear elements and can make two signal multiplied so that it can implement frequency transformation. This article analyses the applications and procedures in frequency transformation of multiplier from principle.
