摘要：

A new technique for designing FIR filters where the desired frequency response is a smoothed rectangular function is proposed. Instead of choosing a suitable window in time domain, we will directly try smoothing the ideal desired response in frequency domain. The impulse response of the FIR filter is a sampled version of the inverse Fourier transform of the frequency response. In comparison with results reported in the literature, this technique provides the best performance in terms of filter specifications.
