Description: The Zoom-FFT is a process where an input signal is mixed down to baseband and then decimated, prior to passing it into a standard FFT. The advantage is for example that if you have a sample rate of 10 MHz and require at least 10Hz resolution over a small frequency band (say 1 KHz) then you do not need a 1 Mega point FFT, just decimate by a factor of 4096 and use a 256 point FFT which is obviously quicker.

Description: ZOOM-FFT称为细化的快速傅立叶变换，又称为选带快速傅立叶变换。ZOOM-FFT的功能是对信号的频率进行局部细化放大，使感兴趣的频带获得较高的频率分辨率。实现FFT细化功能的算法有几种，如频移法-、相位补偿法和最大熵谱法等，目前应用最关的是频移法(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)
