Optimization of Butterworth and Bessel Filter Parameters with Improved Tree-Seed Algorithm

open access: yesBiomimetics, 2023
Filters are electrical circuits or networks that filter out unwanted signals. In these circuits, signals are permeable in a certain frequency range. Attenuation occurs in signals outside this frequency range.
