本文介绍一组通用干扰图。在无线电工程系统设计中,当接收机工作频段已经给定时,如果要求选择无干扰中频及一本振主振器工作频段(或倍频次数),则利用本文所推荐的通用干扰图来寻求答案是非常简单、容易、直观和迅速的。文章扼要介绍了通用干扰图的构成原理,并以工程中的实例说明了干扰图的使用方法和效果。
This article describes a common set of interference graphs. In the radio engineering system design, when the receiver operating band has been given, if you want to select the interference free IF and a vibration frequency band (or frequency multiplier), the use of the recommended common interference diagram to find the answer It is very simple, easy, intuitive and rapid. The article briefly introduces the principle of the general interference graph, and illustrates the use method and effect of the interference graph with examples in the project.
