In this paper, we will address the question of how to design a continuous-time filter that provides both a constant delay and a maximally flat magnitude response over the desired frequency band, and at the same time ensures the transient of the designed filter as short as possible. The paper presents a theoretical concept of timevarying Butterworth filters with compensated group delay response. Using the compensated Butterworth filter, we introduce time-varying parameters to its structure for the purpose of the minimization of the transient that was lengthened because of the process of the compensation. Results verifying the effectiveness of the proposed approach are presented and compared to the traditional filters. This paper is an updated and extended version of Piskorowski, J. (2006). Analog Integrated Circuits and Signal Processing, 47, (2):233-241.
