In connection with phase error on FFT computation, the correction formula of phase is derived by mathematical method. The FFT phase correction module is based on TMS320F2812 DSP as control and process core. The data before and after correction which are computed by DSP and accurately compared are sent to PC through the serial port RS232. The practical results illustrated that this method is feasible and effective.
