內容概要
本書介紹了Δ∑模數(shù)及數(shù)模轉換器的原理,引入了計算機輔助分析和設計技術。由于Delta-Sigma數(shù)據轉換的原理有著廣泛的應用范圍,不僅限于數(shù)據轉換器,所以本書涉及面廣,包括數(shù)字電話、數(shù)字音頻、無線及有線通信、醫(yī)療電子等中的Δ∑轉換器。作者強調實際操作而不是復雜的數(shù)學推導,通過一階Δ∑調節(jié)器引出二階及高階調節(jié)器,同時討論了實現(xiàn)方法,給出了設計實例。本書從基本概念開始,由淺入深地介紹了Delta-Sigma轉換器,并結合實例幫助讀者理解,因此適應各個層次的研究者,既適合于Delta-Sigma數(shù)據轉換的初學者,同時適合高年級本科生和研究生。
