Comments on "A new hardware realization of digital filters"
Bu-chin Wang · IEEE Transactions on Acoustics Speech and Signal Processing · 1977
The purpose of this short note is to point out that in the above paper the operation speed (word rate) of infinite-duration impulse-response (IIR) filters is different from that of the finite-duration impulse-response (FIR) filters, and in the high-speed realization case, the difference is even larger.
