摘要:

本文分析了音乐信号自适应加重网络增量调制(ΔM)的原理和适用性,从理论上推导了自适应加重网络的传递函数表达式,且描绘了音乐信号的加重曲线,并得出了在工作频率为3KHz可提高信噪比约7dB的结论。在文章的最后给出了整个自适应加重网络实现的具体框图和部分电路。

Theory and practice ot music signal in delta modulation of adaptive weighted network

()

Abstract:

This paper analyzes the theory and practice of mnsic signal in delta modulation of adaptive weighted network. Transfer function expression for adaptiveweighted network was derived from theory and weighted curve of music signal was described. Conclusion increasing 7dB S/N at 3KHz operation frequency is given in the paper. Finally, all the diagram and part circuit of adaptive weighted network are given.
