which improve the structure of normal FFT algorithm
and change concentrated operation into unequally operation among gaps of sampling points.When sampling frequency is comparatively high and sampling windows are relatively long
it can implement continuous sampling of measured signal and continuous FFT analysis.The method uses hardware PLL（Phase-Locked Loop）to synchronize the sampling window and the measured signal cycle exactly.It is based on high-speed DSP（Digital Signal Processor）TMS320C32-60in order to implement recursive FFT algorithm
then give the results
which shows the possibility to realize the continuous sampling of signals.
