If the sampling frequency is less than this, we can expect a serious distortion of output frequency which is generally referred to as aliasing . 如果取樣頻率小于此數(shù),那么輸出頻率就要產(chǎn)生嚴(yán)重畸變,通常假頻指的就是這種情況。
Secondly , alterability of sampling frequency was required in the work of this paper 其次,本課題還要求采樣率可變。
