Approximate design relationships for low-pass FIR digital filters
L. R. Rabiner · IEEE Transactions on Audio and Electroacoustics · 1973
In this paper, a set of simple, approximate relationships between FIR, linear phase, low-pass filter parameters is presented. Based on these relationships, it is shown how an existing, readily available, filter design program can be used to efficiently design low-pass filters that meet or exceed arbitrary input specifications.
