| Abstract: | This paper addresses the problem of designing linear-phase finite impulse response digital filters using an $L_1$ optimality criterion. An efficient procedure for the design of such filters is proposed and it is shown that the resulting filter several desirable properties. Specifically, $L_1$ filter possesses flat passbands and stopbands while keeping the transition band comparable to that of least-squares filters. A comparison with existing methods is made, and it is shown that our method is as efficient as the celebrated Remez exchange algorithm. | ||
