Design and analysis of recursive filters with optimum clutter rejection using zero frequency initialization

Design and analysis of second order IIR notch filters with double frequency initialization

“…However, it can be used to design filters with optimum transient performances [10]. This paper deals with the design of new filters with an initialization processor which can force the steady state response at two frequencies while optimizing the transient response at other frequencies.…”

Reduced aperture radar signal processing

“…Therefore, the IIR array, with the investigated initialisation methods, do not perform better than an equivalent FIR filter designed with the optimal Dolph-Chebyshev weightings. Other initialisation methods do still exist [40][41][42] and it may be worth investigating if they can possibly bring about any improvement over the optimal FIR filter, hence increasing the performance of the IIR array.…”
