Abstract :
The block Z transform (BZT) is presented. It is shown that the BZT, used with the modified Fermat number transform (MFNT), is very efficient for FIR filtering of a long impulse response. The BZT takes advantage of the number theoretic transforms (NTTs), namely, the computational efficiency, and overcomes use of the restrictions on the NTTs, namely, the restriction on the length of the impulse response
