Matlab Implementation in ZOOM FFT Technology Based on Analytic Signal and Band-Pass Filter

摘要

ZOOM FFT technology is widely used in signal processing and modal analysis, it can improve frequency resolution, and amplify the characteristic curve in selected regions, makes the frequency characteristic of the system more clearly shown. ZOOM FFT technology based on analytic signal and band-pass filter has greatly improved than traditional methods, provides a new way to virtual instrument based on computer platform. This article discusses the application of Matlab to achieve the ZOOM FFT.
