For digital equalization algorithm, using the parametric equalizer design method. 对于数字均衡算法,采用的是有关参量均衡器的设计方法。
The method of realizing a high quality audio playback system for railway transportation using digital signal processing technology and CODEC ( Coder and Decoder ) chip is introduced in this article. The parametric equalizer, which consists of all-pass filter, is achieved on the DSP platform. 文中主要介绍了一种利用数字信号处理技术结合CODEC芯片实现轨道交通高音质音频播放系统的方法,以及在DSP上实现的由全通网络构成的音频参量均衡器。
Design of digital parametric equalizer based on function prototype 基于原型法的数字参量均衡器设计
The design of parametric equalizer has its peculiarity because of its particular amplitude to frequency feature and its parameters adjustment way. 由于参量均衡器对滤波器的频响要求及参数调节方法有其特殊性,因此它的设计方法也有其自身的特点。
