High word-rate digital filters with programmable table look-up
H. Schröder · IEEE Transactions on Circuits and Systems · 1977
Recently proposed methods of implementing digital filter sections using table look-up were investigated for the purpose of realizing fast variable digital filters. An address method that takes as an address all the bits ofiequal binary weights of the address variables is highly practical for variable filters because it allows a simple computing and loading process for the data stored in the memory.
