Assuming that the original signal sample rate is 4000kHz, a set of 1 harmonics consisting of a 200Hz fundamental, which is simulated by the sine function.Thus get 200hz,400hz,600hz ... 2000Hz, but the magnitude of the 2000Hz here is almost 0, which is explained in detail later.Time domain waveform with a 200Hz amplitude of 1. FFT transformation, the amplitude of the corresponding frequency is still 1, the frequency is still 200Hz, the mirror frequency symmetry, at the frequency (4000-2000) Hz di
