WebBessel Filters. Bessel filters are optimized for maximally-flat time delay (or constant group delay). This means that they have a linear phase response and excellent transient response to a pulse input. This comes at the expense of flatness in the pass-band and rate of roll-off. The Bessel filter is only available with low pass selectivity. WebIn Op Amp Applications Handbook, 2005. Bessel. Butterworth filters have fairly good amplitude and transient behavior. The Chebyshev filters improve on the amplitude response at the expense of transient behavior. The Bessel filter is optimized to obtain better transient response due to a linear phase (i.e., constant delay) in the pass band. This ...
