WebThe Bessel low-pass filters have a linear phase response (Figure 16 – 7) over a wide fre-quency range, which results in a constant group delay (Figure 16– 8) in that frequency range. Bessel low-pass filters, therefore, provide an optimum square-wave transmission behavior. However, the passband gain of a Bessel low-pass filter is not as flat ... WebHigh pass filters use the same two topologies as the low pass filters: Sallen–Key and multiple feedback. The only difference is that the positions of the resistors and the capacitors have changed. As with the low pass filters, higher order high pass filters are designed by cascading first order and second order filter stages.
