通常指一種內裝數字分頻網路和功率放大器的音箱。數字式音箱輸入的信號為數字比特流,在用數字信號處理的方法將音頻頻譜分割后,便分別將這些信號變換為模擬信號,然後再由各自的功率放大器放大后再去推動音箱中的相應發音單元。Voice - frequency receiving amplifier
音頻接收放大器In the thesis, a high efficiency linear am amplifier is developed, which is based on the basic theory of eer linearization amplifier technique [ 1 ]. the high efficiency digital audio amplifier technology [ 2 ] is adopted to develop the power supply modulator and the class - d switching amplifier technology [ 3 ] is adopted to develop the high efficiency rf amplifier
本論文利用eer ( envelopeeliminationandrestoration )線性功放技術的基本原理[ 1 ] ,採用數字音頻功放技術[ 2 ]實現高效率電源調制器,採用class - d開關放大技術[ 3 ]實現高效率載頻放大器,開發了一個集am調制和放大於一體的高效率線性功率放大器。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。Because of their inability to move large volumes of air, they are limited to reproducing only very high frequencies, and are therefore used only as tweeters
由於等離子喇叭不能推動大量的的空氣,只適用於非常高的頻率聲音重放,因而只能當高音喇叭。In addition, the author puts forward that the eggs could be recognized based on the difference in the frequencies of their prompted sounds. because the eggs " prompted sounds are lied on low frequency bands, the microphone and sound amplifier that have excellent duration response should be used. the output signal from the sound amplifier is transferred to data signal by a / d card before it is put into computer
蛋品激勵出的聲音主要集中在低頻段,因此選擇在低頻段有好的頻率響應特性的麥克風和放大電路;放大輸出信號通過a / d採集板變換成相應的電壓數值信號送入計算機,對離散的信號數據進行傅立葉變換得到它的頻譜圖和各頻段能量分布圖;而後將能量分佈特徵數據作為神經網路的輸入值,這樣,好蛋和破損蛋的模型就建立起來。Sound waves from the iceberg had a frequency of around 0. 5 hertz, too low to be heard by humans, but by playing them at higher speed the iceberg sounded like a swarm of bees or an orchestra warming up, the scientists said
