Abstract

Using Laguerre networks in the discrete-time (DT) domain has already been addressed by Masnadi-Shirazi and Ahmed (1991). The main contribution of the present paper is to use the Laguerre networks in the frequency domain, and to design digital filters based on the specified frequency response. This filter design yields an appropriate linear phase, with lower ripples in the stopband and passband compared to conventional FIR filters. Both analytical and numerical approaches for Laguerre digital filter design are introduced in detail and the results are shown through some examples. The procedure is based on minimizing the mean-square-error (MSE) between the frequency response of the desired filter and its corresponding Laguerre network frequency response
