电视发射技术中环形变频器的实际变频器电路研究
资料介绍
在电视发射技术中,要把图像中频调幅信号和伴音中频调频信号变换成规定发射频道的高频调制信号,就要采用变频器才能实现,变频器的作用是实现频率变换。阐述了变频器的分类,研究了环形变频器的实际变频器电路等技术问题。
In TV transmission technology,if we want to convert the image FM signal and the accompanying sound FM signal into the high frequency modulation signal of the specified transmission channel,we need to use the frequency converter to realize it. The function of the frequency converter is to realize the frequency conversion. This paper expounds the classification of frequency converters,and studies the practical frequency converter circuit of ring converter and other technical problems.
