output frequency的用法和樣例：
例句
- You can use Enable to lower the output frequency by connecting it to a prescaler.
通過(guò)連接前置比例器，使用使能來(lái)降低輸出頻率。 - 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，那么輸出頻率就要產(chǎn)生嚴重畸變，通常假頻指的就是這種情況。
