Designing Audio Circuits and Systems (音頻電路與系統設計)

《設計音頻電路與系統》是一本全面介紹音頻電路與系統設計的指南。這本書從初學者能夠理解的類比音頻電路設計基礎開始，提供了深入的設計技術，涵蓋了許多不同的音響愛好者和專業音頻電路及功能。

Bob Cordell is an electrical engineer who has been deeply involved in audio since his adventures with vacuum tube designs in his teen years. He is an equal-opportunity designer to this day, having built amplifiers and preamplifiers with vacuum tubes, bipolar transistors, JFETs and MOSFETs, and is a prolific designer of audio test equipment, including a high-performance THD analyzer and many purpose-built pieces of audio test gear. He has published numerous articles and papers on power amplifier design and distortion measurement in the popular press and in the Journal of the Audio Engineering Society. In 1983 he published a power amplifier design combining vertical power MOSFETs with error correction, achieving unprecedented distortion levels of less than 0.001% at 20 kHz. He previously published the book Designing Audio Power Amplifiers.

Bob is an avid DIY loudspeaker builder and has combined this endeavor with his electronic interests in the design of powered audiophile loudspeaker systems. He also consults in the audio and semiconductor industries and has presented audiophile listening and measurement workshops with his colleagues at the Rocky Mountain Audio Fest and the Home Entertainment Show. As an electrical engineer, Bob has worked at Bell Laboratories and other related telecommunications companies, where his work has included design of integrated circuits and fiber optic communications systems. Bob holds 17 patents and has presented numerous papers at the International Solid State Circuits Conference (ISSCC), the Convention of the Audio Engineering Society and other related professional meetings. Bob maintains an audiophile website at www.cordellaudio.com where diverse material on audio electronics, loudspeakers and instrumentation can be found.

Bob Cordell 是一位電機工程師，自青少年時期開始便深深投入音頻領域，當時他便開始探索真空管設計。至今，他仍是一位平等機會的設計師，曾使用真空管、雙極性晶體管、JFET 和 MOSFET 建造放大器和前置放大器，並且是音頻測試設備的多產設計師，包括高性能的總諧波失真 (THD) 分析儀以及許多專門設計的音頻測試設備。他在流行媒體和《音頻工程學會期刊》上發表了大量有關功率放大器設計和失真測量的文章和論文。1983 年，他發表了一種結合垂直功率 MOSFET 和誤差修正的功率放大器設計，實現了在 20 kHz 下低於 0.001% 的前所未有的失真水平。他之前出版過一本書《設計音頻功率放大器》。

Bob 是一位熱衷於 DIY 音箱建造的人，並將這項工作與他在設計有源音響音箱系統方面的電子興趣結合起來。他還在音頻和半導體行業提供諮詢，並與同事在洛基山音頻節和家庭娛樂展上舉辦了音響愛好者的聆聽和測量工作坊。作為一名電機工程師，Bob 曾在貝爾實驗室及其他相關的電信公司工作，他的工作包括集成電路和光纖通信系統的設計。Bob 擁有 17 項專利，並在國際固態電路會議 (ISSCC)、音頻工程學會大會及其他相關專業會議上發表了多篇論文。Bob 維護著一個音響愛好者網站 www.cordellaudio.com，網站上有關於音頻電子學、音箱和儀器的各種資料。
