Note
The smaller the width of the rejection band, the more ripples are in the surrounding frequencies
amplitudes. However, the area of the phase shift is smaller as is the signal attenuation at the rejection
band. It is recommended to use a rejection band width of at least 8 Hz in order to avoid overshoot.
The bigger the width of the rejection band, the smoother is amplitude transition around the central
frequency. Additionally, the attenuation is bigger. This happens due to the second order of the filter
which has limited attenuation per decade. However, the phase delay region is bigger.
