FM stereo broadcasting was introduced, further enhanced the broadcasting services. 开始短波调频立体声广播,进一步提高广播服务。
High-efficiency transmitter for MW SSB stereo broadcasting 中波单边带立体声广播的高效率发射
Research on Medium Wave Amplitude Modulation Stereo Broadcasting Systems in China 中波调幅立体声广播制式研究
The MW SSB stereo broadcasting system requires high efficiency of the transmitter which usually employs high power amplifier, as the high quality of information transmission is important. 中波单边带立体声广播发射系统,除要求高质量传送信息外,由于其发射功率较大,因此,如何提高发射机效率也是至关重要的问题。
In this paper, first the usual modes for dual sound/ stereo TV broadcasting are introduced, then basic principle of NICAM dual sound/ stereo TV broadcasting system is analysed and the integrated circuit used in the receiving system is given. 本文首先介绍了电视双伴音/立体声广播的几种常用方式,然后着重分析丽音(NICAM)双伴音/立体声广播系统的基本原理,并给出其接收系统的集成电路。
