Abstract： |
This invention discloses a method for realizing time domain used in FIR filters including: decomposing the impulse response of a FIR filter into multiple sub-impulse responses with fixed length and decomposes each of the sub-one into multiple segment sub-impulse responses with fixed length and then multiple segment sub-linear convolution results are got after the input signal of the filter passes through each of the sub-segment impulse response then the selected results are put together to get multiple sub-linear convolution results and then to be delayed and added to get a time domain output signal of the FIR. |
