Abstract: This paper introduces new multirate infinite-length impulse-response (IIR) filter structures for arbitrary bandwidths. The overall filters have the same input and output sample rates.
Abstract: This paper introduces new multirate approximately linear-phase IIR digital filter structures for arbitrary bandwidths. The overall filters have the same input and output sample rates.
Infinite impulse response (IIR) filter implementations can have different forms (direct, standard, ladder, …), different math (fixed-point or floating-point), and different quantization (number of ...
