Abstract

In the article an example of LC coupled resonator filter is considered. Sensitivity analysis is used to estimate distortion of amplitude response caused by finite value of Q factor of LC resonators the circuit consists of. As a result a generalized version of formulas for distortion of amplitude response, is formulated. Next improved version of predistortion technique is presented. Predistortion is used to construct filters adhering given shape of frequency response using elements with finite value of Q factor.
