Description: In the frequency spectrum analysis of refined band selection, ZFFT and Chirp-Z transform are two commonly used methods. For the dense multi frequency harmonic components with serious interference, ZFFT can obtain high-precision signal parameters by increasing the thinning multiple and resampling, separating the frequency components of interference and correcting them.

Description: Fast Fourier transform (FFT) is a fast method to calculate the discrete Fourier transform (DFT) of a sequence or its inverse transform. Fourier analysis transforms a signal from its original domain (usually time or space) to its representation in the frequency domain or vice versa. FFT can calculate these transformations quickly by decomposing DFT matrix into product of sparse (mostly zero) factors.

Description: "FFT = fast fourior transform. This is a fast Fourier transform that is convenient for computer calculation. There is also a DFT, but because of its complexity = N ^ 2 >> FFT = NlogN, it is not used by computer algorithms. The purple one is the above. The corresponding value of the wave in the frequency domain (spectrum) We know that the square wave can use Fourier series ... "
