Algorithm for the design of multi-input filters with parameter uncertainty
Adrain Ioinovici, I. M. HOROWITZ · International Journal of Electronics · 1985
A design method is developed for multi-input filters with components subject to a statistical distribution of their parameter values, due to manufacturing tolerances and variation in the operating environment. The circuit with uncertain component parameters is embedded in a feedback structure, which is designed to achieve the system specifications, despite the uncertainty. A two-input filter example illustrates the design theory.
