Channel Step Response
Another module characteristic determined by filter frequency is channel step
response, as shown in the following table. The step response is the time
required for the analog input signal to reach 100 percent of its expected final
value, given a full-scale step change in the input signal. Thus, if an input signal
changes faster than the channel step response, a portion of that signal will be
attenuated by the channel filter. The channel step response is calculated by a
settling time of 3 x (1 / filter frequency).
