Using FFT and complex filtering, real bandpass signal can be recovered as a analytic signal whose central frequency is within two times of its bandwidth, and phase property is not changed. Finally, using simple computation, original frequency can be acquired. Computer simulation shows the correction of the method. %K Nonuniform sampling %K FFT %K Interpolation recovery %K Aliasing %K Frequency-shifting
