本文作者分析了采用扫频仪法调试电视机伴音电路,由于扫频仪的扫频速度快和电视机电路的惯性,使鉴频S曲线滞后而造成失真,并根据35HD-2型机的具体情况改进调试方法,从而提高了伴音的音质。本文第一稿编辑部是1983年初收到的,其后几经修改。编辑部认为,本文阐述的问题是作者辛勤劳动的成果,其思考方法有一定参考价值。现征得作者本人同意,刊登出来供有关读者参考。
The author analyzes the use of sweep-frequency method to debug TV sound circuit, due to the swept frequency of the sweeper and the inertia of the TV circuit, so that the frequency of S-curve lag caused by distortion, and 35HD-2-based machine-specific The situation improves debugging methods, thus improving the sound quality of the sound. The first draft of the editorial department was received in early 1983, after several changes. The editorial department believes that the problem described in this article is the result of the hard work of the author and his method of thinking has some reference value.
