ZOOM-FFT is called a thinned Fast Fourier Transform, also known as Fast Fourier Transform. The function of ZOOM-FFT is to partially refine and amplify the frequency of the signal so as to obtain the higher frequency resolution of the frequency band of interest. There are several algorithms to achieve FFT refinement, such as frequency shift -, phase compensation and maximum entropy spectral method, the current application of the most relevant is the frequency shift method
