Practical design rules for optimum FIR bandpass digital filters
Fred Mintzer, Bede Liu · IEEE Transactions on Acoustics Speech and Signal Processing · 1979
The computer program of [1] for the design of optimal FIR filters requires, as an input, the order of the filter to be designed. A reliable order estimate for the case of low-pass filters is known [2]. In this paper, we present a simple estimate of the order of optimum FIR bandpass filters. The accuracy of the estimate is demonstrated.
