Figure 6: Hardware filter response with  Hz and  Hz. Panel (a) shows the amplitude response, while panel (b) shows a smooth phase response without jumps by adding multiples of 360. The black dots show the real transfer function from the injected experiment with a blue line representing the best fitting of the amplitude and phase response, while the red line shows the theoretical Bessel filter response.
