A new design method of optimal finite wordlength linear phase FIR digital filters
J. Marques de · IEEE Transactions on Acoustics Speech and Signal Processing · 1983
The branch and bound technique is applied to the design of optimal finite wordlength linear phase FIR digital filters in a new efficient way. Compared to other reported methods there is a great saving of storage area used by the designing program; reductions in computation time are also to be expected.
