The shape of the magnitude and phase responses of a filter impacts how signals look in the time domain. The step response of a filter is typically used to identify the behavior of a filter in the time domain.
Three important factors of the filter step response are group delay, rise time, and overshoot/undershoot. The three filters differ instep response across signals in the transition band:
Refer to the FD-116xx Specifications for details on the amount of variation in the response you can expect for different input frequency ranges.
