On maximally-flat linear-phase FIR filters
Palghat P. Vaidyanathan · IEEE Transactions on Circuits and Systems · 1984
An implementation for maximally-flat FIR filters is proposed that requires a much smaller number of multiplications than a direct form structure. The values of the multiplier coefficients in the implementation are conveniently small, and do not span a huge dynamic range, unlike in a direct form implementation.
