Frequency sampling filters with algebraic integers
Uwe H. Meyer-Baese, J.D. Mellott, Fred J. Taylor · 2002
Algebraic integers have been proven beneficial to DFT and non-recursive FIR filter designs since algebraic integers can be dense in C, resulting in short word width, high speed designs. This paper uses another property of algebraic integers: algebraic integers can produce exact pole zero cancellation pairs that are used in recursive FIR, frequency sampling filter designs.
