Designing Audio Circuits and Systems

「設計音頻電路和系統」是一本關於音頻電路和系統設計的全面指南。從初學者可以理解的模擬音頻電路設計基礎開始，本書提供了深入的設計技巧，適用於多種不同的音響愛好者和專業音頻電路和功能。

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是一位電氣工程師，從十幾歲時開始就深入涉足音頻領域，並對真空管設計充滿熱情。至今，他仍然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等元件建造放大器和前級放大器，並且是一位多產的音頻測試設備設計師，包括高性能的THD分析儀和許多專用的音頻測試設備。他在大眾媒體和《音頻工程學會期刊》上發表了許多關於功率放大器設計和失真測量的文章和論文。1983年，他發表了一種將垂直功率MOSFET與誤差校正相結合的功率放大器設計，實現了在20 kHz下不到0.001%的前所未有的失真水平。他之前還出版了書籍《設計音頻功率放大器》。

Bob是一位熱衷於自製喇叭的愛好者，並將這一努力與他對電子的興趣相結合，設計了動力音響愛好者用的喇叭系統。他還在音頻和半導體行業提供諮詢服務，並與同事一起在Rocky Mountain Audio Fest和Home Entertainment Show上舉辦音響聆聽和測量研討會。作為一名電氣工程師，Bob曾在貝爾實驗室和其他相關電信公司工作，他的工作範圍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）、音頻工程學會大會和其他相關專業會議上發表了許多論文。Bob在www.cordellaudio.com上維護著一個音響愛好者網站，該網站提供了關於音頻電子、喇叭和儀器的多樣資料。
