frequency sampling filters 中文意思是什麼

frequency sampling filters 解釋
頻率抽樣濾波器
  • frequency : n. 1. 屢次，頻仍，頻繁。2. （脈搏等的）次數，出現率；頻度；【物理學】頻率，周率。
  • sampling : n. 1. 取樣（品），取標（本）〈指行動或程序〉。2. 樣品，標本。3. 剽竊拼湊歌曲。
  1. Moreover, sampling at high frequency eliminates the need for abrupt cutoffs in the analog anti - aliasing filters. a technique of noise shaping is used in - converters in addition to oversampling to achieve a high - resolution

    由於在- a d轉換器中使用噪聲整形技術和過采樣技術，可以用一個簡單的模擬電路加上復雜的數字電路使整個a d達到一個很高的轉換精度。
  2. We propose a chaos - based generation of the random ppm - ps signals, design and implement a generator of the ppm - ps signals. we introduce an if sampling technique and simulate the performances of digital demodulation techniques of using hilbert filters, sine filters, bessel filters and poly - phase filters. the poly - phase filtering method can achieve the higher mirror - frequency rejection ratio by using the low order filters

    介紹了中頻采樣技術，並對希爾伯特濾波法、辛格內插函數修正、貝賽爾函數插值法及多相濾波法等數字解調演算法進行了計算機模擬和性能比較，指出多相濾波法能以較低的階數實現較高的鏡頻抑制比。
