Very low sensitivity recursive digital filter structures
Laxmi Narayan Bhuyan, Biswa Nath Chatterji · Electronics Letters · 1981
A type of realisation of recursive digital filters is proposed here to give very low-magnitude transfer function sensitivity with respect to multiplier coefficients. Simulation results of sensitivity values for a simple 2nd-order filter are presented and compared with some of the existing realisations to show the order of improvements.
