4-6 Preliminary Operating Considerations
Channel Step Response
The channel filter frequency determines the channel’s step response.
The step response is time required for the analog input signal to reach
100% of its expected final value. This means that if an input signal
changes faster than the channel step response, a portion of that signal
will be attenuated by the channel filter. The table on page 4-4 shows
the step response for each filter frequency.
