蔡坤寶博士,重慶大學通信工程學院教授,信號與信息處理碩士學位點負貴人。長期從事信號與信息處理的教學與科研工作。近十餘年來,積極探索和實施中英文雙語教學,現任重慶大學大類係列課程“信號與係統”建設項目負責人,重慶市精品課程“信號與綫性係統”負責人、雙語教學示範課程“信號與係統”負責人,並承擔重慶市精品課程“數字信號處理”的建設工作。
這本《數字信號處理(第2版)(英文版)》的教材,初拿到手時,我最直觀的感受就是它的“厚重感”。從排版到內容深度,都透著一股嚴謹的學術氣息。作為一名在校的電子信息工程專業學生,我深知DSP是理解現代通信、圖像處理乃至人工智能底層邏輯的關鍵。這本書的結構安排非常閤理,它沒有一上來就拋齣那些令人望而生畏的復雜公式,而是先用非常直觀的例子和清晰的數學背景知識鋪墊,比如對傅裏葉分析的復習和離散時間係統的基本概念,這對於我這種基礎不太紮實的讀者來說,是極大的福音。尤其讓我印象深刻的是,它在講解Z變換和離散時間傅裏葉變換(DTFT)時,插圖和推導步驟都做得極其詳盡,即便是初次接觸這些概念,也能順著作者的思路一步步理解其物理意義,而不是僅僅停留在符號操作的層麵。教材中大量的實例,無論是濾波器設計還是譜分析,都緊密結閤瞭實際應用場景,這使得抽象的理論知識變得“有血有肉”,極大地激發瞭我深入學習的興趣。可以說,這本書為我打下瞭一個非常堅實的理論基礎,是教科書中的典範之作。
評分翻閱這本教材的過程中,我發現它在深度和廣度上都做得相當齣色,絕非那種隻停留在錶麵概念介紹的入門讀物。尤其是在高階主題的處理上,比如多速率信號處理和自適應濾波器的章節,作者的闡述深入到瞭算法的核心,並且不迴避那些理論上較為尖銳和睏難的部分。我記得在學習最小均方(LMS)算法時,書中不僅給齣瞭收斂性的證明思路,還詳細對比瞭不同步長選擇對算法性能(如收斂速度和穩態誤差)的影響,這種對細節的把握,讓我在後續做課程設計時能夠更有信心地選擇閤適的工具。此外,書中大量的習題設計也極具挑戰性,它們不僅僅是公式的簡單代換,很多都需要綜閤運用前麵學到的多個知識點進行分析和推導,這極大地鍛煉瞭我的獨立解決問題的能力。對於那些希望未來從事DSP算法研發或更深層次研究的讀者來說,這本書無疑是一份極其寶貴的資源,它所提供的知識深度已經超越瞭普通本科課程的要求,更接近於研究生教材的水準。
評分這本書的另一個突齣優點,是其對理論與實踐結閤的重視程度。雖然是理論教材,但作者並沒有完全脫離工程實際。在講解數字濾波器設計時,從最基礎的頻域指標要求齣發,逐步過渡到時域的係數確定,再到利用Matlab或類似工具進行仿真驗證的流程,講解得環環相扣。我特彆欣賞它在介紹某些高級算法時,會適當地引入一些硬件實現的考慮因素,比如計算復雜度、量化誤差對係統性能的影響。雖然它沒有提供詳細的Verilog或VHDL代碼,但這種對工程約束的提前預警,讓我能夠從一開始就建立起“理論設計”和“實際落地”之間的聯係。這對於我們這些即將步入工程界的學生來說,是彌足珍貴的。掌握的知識不再是孤立的數學公式,而是可以轉化為實際産品和係統的設計藍圖,這極大地提升瞭學習的實用價值和成就感。
評分總體而言,如果將市麵上眾多的DSP教材比作不同風味的菜肴,那麼這本《數字信號處理(第2版)(英文版)》無疑是一道經過精心烹飪、營養均衡的“硬菜”。它在理論的深度挖掘上毫不含糊,確保讀者能夠紮實掌握數字信號處理的數學基礎和核心原理;同時,它在教學方法的編排上又顯得極為老道,通過清晰的邏輯鏈條和豐富的例證,將原本可能晦澀難懂的內容變得層次分明、易於吸收。對於希望係統學習、並能將知識應用於復雜工程問題的讀者來說,這本書的價值是毋庸置疑的。它不僅是一本參考書,更像是一個耐心的導師,引導你一步步跨越從理論到工程實踐的鴻溝。我個人認為,這本書的價值足以支撐它成為任何DSP課程的指定教材,或者作為專業人士案頭必備的工具書。
評分與其他一些教材相比,這套書在“可讀性”方麵確實下瞭一番功夫,盡管它是英文原版,但作者的行文風格非常清晰且富有邏輯性。閱讀過程中,我感覺自己像是在與一位經驗豐富的教授進行一對一的交流。比如在討論窗函數設計時,作者沒有簡單地羅列各種窗函數的特性,而是通過對比理想低通濾波器和實際濾波器之間的誤差來源,自然而然地引齣瞭截斷效應和窗函數的作用,這種“問題導嚮”的教學方式,讓我對設計的初衷理解得更為透徹。再者,書中對於某些關鍵概念的“小貼士”或“注意事項”部分,往往能點齣那些容易讓人混淆的陷阱,比如在進行有限脈衝響應(FIR)和無限脈衝響應(IIR)濾波器的選擇與對比時,作者的比較分析就做到瞭極其到位,明確指齣瞭各自的優缺點和適用場景,避免瞭知識點上的“一鍋燴”。對於自學者而言,這種細緻入微的引導是至關重要的,它能有效降低理解的門檻。
