@article{Misans_Hauka_2005, title={Causes of Collapse of Q-factor and Consequences for DSP Applications}, volume={61}, url={https://eejournal.ktu.lt/index.php/elt/article/view/10442}, abstractNote={<p>Implementation of digital resonator by using of analog prototype and bilinear transformation leads to the effect of collapse of Q-factor. This paper describes the cause of the collapse and presents the formula for calculation of collapse frequency. We also present a simplified method for the compensation of collapse. The main consequence of collapse effect is that the formal using of pre-warping of critical frequencies of analog prototype can be dangerous for the synthesis of digital filters.
