A根據水壓差自動開啟和關閉,安全可靠,無噪音,無需人員操作,無需維護Because of the using of interpolation, noise shaping and switching amplification in the digital audio amplifier technology, the power supply modulator is not only much efficient but also behaving good in envelope amplification, this advantage is hard to implemented with conventional technology
數字音頻功放技術是近年發展起來的高效率音頻放大技術,該放大技術採用了過取樣、噪聲整形等數字音頻處理演算法和開關功率放大。採用該技術實現的電源調制器不但具備很高的效率,而且能高指標地放大包絡信號,是常規的電源調制技術無法實現的。Specifically, this thesis includes the following work : the basic theory of speech processing and noise in speech reduce. we study the short interval character of speech signal and short interval process technology, and classify the noise and disturbance in wireless receiver terminal into 3 categories and present corresponding schemes
