aliasing distortion 解釋
混疊畸變
  • aliasing : 別名判別
  • distortion : n. 1. 歪扭,扭曲。2. 【電學】(信號、波形等的)失真;【物理學】(透鏡成像產生的)畸變;【醫學】扭轉,變形。3. 竄改,歪曲,曲解。adj. -al
  1. Frequency response, quantization noise, reconstruction error and its sensitivity to mismatch among adcs are studied at length in prqmf banks adc system, and the theoretic results include : ( 1 ) the distortion / aliasing functions of hybrid filter banks adc system is similar with that of switch capacitor filter banks adc system ; ( 2 ) for wide or narrow band input signal, the effective resolution of the two adc systems is 0. 51og2m bits higher than their adc ; ( 3 ) reconstruction error ' s sensitivity to mismatch among adcs of the two adc systems is reduced effectively than time interleaved adc system

    2對prqmf濾波器組adc系統的頻響、量化噪聲特性、重建誤差特性以及重建誤差對adc間的失配敏感性進行了理論分析研究,所得到的理論結果為: ( 1 )混合濾波器組adc系統與開關電容濾波器組adc系統的失真/混迭函數一致; ( 2 )無論輸入寬帶還是窄帶信號,這兩種adc系統的有效解析度均比其adc提高了0 . 5log _ 2m比特; ( 3 )這兩種adc系統的重建誤差對其adc間的失配敏感性均明顯低於時間交織adc系統。
  2. If the sampling frequency is less than this, we can expect a serious distortion of output frequency which is generally referred to as aliasing.

    如果取樣頻率小於此數,那麼輸出頻率就要產生嚴重畸變,通常假頻指的就是這種情況。
