數(shù)字信號(hào)處理

K.Mitra所著的《數(shù)字信號(hào)處理(基于計(jì)算機(jī)的方法第4版清華版雙語(yǔ)教學(xué)用書)》增加了一些新的內(nèi)容，壓縮了一些已有的內(nèi)容，對(duì)有些材料作了重新安排。我們相信，新版本里每章材料的安排更加符合邏輯，新增加的一些例題，有助于說(shuō)明新的困難的概念。本書很重要的一個(gè)特點(diǎn)是，深度使用MATLAB，通過(guò)說(shuō)明該程序的強(qiáng)大功能的例題，來(lái)解決信號(hào)處理的問(wèn)題。本書使用一種三段式的教學(xué)方法結(jié)構(gòu)，充分利用MATLAB的優(yōu)越性，力求避免用“照貓畫虎”的方法來(lái)求解問(wèn)題的缺憾。
