Using a step input change to illustrate the filter response, as shown in the
illustration, you can see that when the digital filter time constant elapses, 63.2%
of the total response is reached. Each additional time constant achieves 63.2% of
the remaining response.

High Engineering/Low Engineering
High engineering and low engineering values help determine the engineering
units the signal values scale into. The high engineering term corresponds to the
high signal value, while the low engineering term corresponds to the low signal
value. The scaling equation used is shown below.
