數(shù)字信號處理

內(nèi)容概要

Sanjit
K.Mitra所著的《數(shù)字信號處理(基于計算機的方法第4版清華版雙語教學(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，有助于說明新的困難的概念。本書很重要的一個特點是，深度使用MATLAB，通過說明該程序的強大功能的例題，來解決信號處理的問題。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”的方法來求解問題的缺憾。

If h [n] denotes its impulse response, show thatFrom the above result, show that Pn = h[n] dn. 4.50 Consider a causal FIR filter of length L + 1 with an impulse response given by {g[n]}, n = 0, 1 L. Developthe difference equation representation of the form of Eq.
