Abstract：FRFT (Fractional Fourier Transform ) is a good filtering processing tool .Using FRFT to process the signal is a signal filtering method that based on the time-frequency plane rotary .From the signal in the time-frequency plane rota-tion specific angle ,the signal is made degradation in the new time-frequency planefor single frequencysine signal to do pro-cessing ,making signal-noise separation .A reverse rotation recovers the singal without noise .Through the argumentation and the simulation results ,this method not only has obvious offect but also is simple ,and has small amount of calculation . Compared with other fiteringalgorithm ,this algorithm has low computation and is easy to implement .
