在数字条幅中波广播的发射装置中,调制编码器是一个保证广播信号正常发射的一个必备的条件,它主要是对转换电路中送来的各种数字音频信号进行有效的编码。当前,广播信号发射的过程中比较常见的是PDM和DAM的中波发射机,在这些新技术当中,DAM发射机会受到越来越多广播人的青睐和使用,本文主要分析了10k WDAM广播发射机的编码调制技术,以供参考和借鉴。
Modulation encoder is a necessary condition to ensure the normal transmission of broadcast signal in the transmitting device of digital banner medium wave broadcasting. It mainly encodes the various digital audio signals sent from the conversion circuit effectively. Currently, the broadcast signal transmission process is more common in the PDM and DAM medium-wave transmitters, among these new technologies, DAM transmitters will be more and more broadcasters of all ages and the use of this paper mainly analyzes the 10k WDAM broadcast emissions Machine coding modulation technology, for reference and reference.
