【Abstract】 The frequency simulation method is presented in this paper. Under the condition that the sampling theorem in time and frequancy domain is met. Frequency sample on the system and typical input signals is fulfilled. Then, according to the DFT principle simulation results are obtained via reverse transformation. FFT is applied in this algorithm. Finally comparison between this method and the traditional time domain simulating method is given.更多还原
