Abstract :
Fast recovery and frequency-shifting of real bandpass signal based on second-order sampling is discussed. Using FFT and complex filtering, a real band-pass signal can be recovered as an analytic signal whose central frequency is within two times its bandwidth, and phase property is unchanged. Lastly, using simple computation, the original frequency can be acquired. Computer simulation shows the correctness of the method
