| Abstract(in English) | Recently, how to reduce the phase delay of a FIR filter has been studied intensively. For maximally flat lowpass FIR filters, analytic techniques have been developed to drop phase linearity outside the passband. The resulting filters have lower delay in the passband compared with linear-phase FIR filters with the same degree. However, the design method of lowpass FIR filters with maximally flat amplitude and low delay in the passband and the transmission zeros in the stopband has not been proposed. We present the transfer function of lowpass FIR filters with maximally flat amplitude and low delay in the passband and the transmission zeros in the stopband. Because of the closed form transfer function, a design method of these filters is extremely simple. |
