K. S. S. Prasad, Chikkannan Eswaran, A. Antoniou · Journal of Circuits Systems and Computers · 1993
New first-order complex digital-filter sections are realized using the concept of the generalized-immittance converter. These sections are then employed for the realization of infinite impulse response digital filters with real coefficients. The filters obtained with the proposed sections have sensitivity and roundoff noise properties that are comparable to those of other structures of this class reported earlier.
