This book originated from a training course for engineers at the research and developmentcenter of TELEBRAS.the forlTler Brazilian telecommunications holding．That course wastaught by the first author back in 1987，and its main goal was to present efficient digitalfilter design methods suitable for solving some oftheir engineering problems．Later on，thisoriginal text was used by the first author as the basic reference for the digital filters anddigital signal processing courses of the Electrical Engineering Program at COPPE／FederalUniversity of Rio de Janeiro．

迪尼茲編著的《數字信號處理》將理論與實際有機融合，涵蓋了數字信 號處理(DSP)分析和設計的所有重要內容，提供了數字信號處理這一前沿技 術領域難得的設計理念和方法。《數字信號處理》不僅可作為高等院校電子 、通信等專業本科生或研究生教材，還可作為工程技術人員DSP設計方面的 參考用書。 第2版在上一版的基礎上，擴充了濾波器組和小波分析的內容，新增了 隨機信號處理、譜估計和求解差分方程的內容，數學推導中給出了易於讀者 理解的步驟。第2版還提供了120個範例、20個案例研究、約400道練習題。 此外，第2版還有一大新特點——每章末增加了一節“Do-it-Yourself”， 使讀者通過MATLAB實驗獲得解決實際信號處理問題的親身體驗。
