一、概述近年来,随着立体声收录设备的大量生产,为了保证产品质量,无论是在生产车间的调试过程中或是产品售出后的检修中,有一台功能全、使用方便、价格便宜的调频立体声信号源是至关重要的。为此我们研制了803型凋频立体声信号发生器,其性能能满足在国内使用的收录机的技术要求。本文就该机的主要技术要求、设计考虑、几个主要部分的设计计算等内容作一简单介绍。
First, an overview In recent years, with the mass production of stereo recording equipment, in order to ensure product quality, whether in the debugging process of the production workshop or the maintenance of the product after the sale, there is a full-featured, easy to use, cheap FM stereo source is crucial. To this end, we have developed a 803 type of fader stereo signal generator, whose performance can meet the technical requirements of the tape recorders used in the country. In this paper, the main technical requirements of the aircraft, design considerations, the design and calculation of several major parts for a brief introduction.
