ABSTRACT:
In an IIR digital filter, the same polynomial is multiplied to both the denominator and the numerator of the system function for the IIR digital filter so as to eliminate the first order term from the denominator of the system function. Thereby, an IIR digital filter for a high-speed signal can be attained using an operation element of relatively low speed and small power consumption.
