These are the non-fundamental frequency components of a distorted 50 Hz waveform. They have frequencies which are integral multiples of the 50 Hz fundamental frequency.
在畸变的50Hz波形中存在非基频的分量。这些频率是50Hz基波频率的整数倍。
If the sampling frequency is less than this, we can expect a serious distortion of output frequency which is generally referred to as aliasing.
如果取样频率小于此数，那么输出频率就要产生严重畸变，通常假频指的就是这种情况。
