Filter Time Constant

A time filter smooths an input signal by sampling the input at designated time
intervals. Either the viewed value or both the viewed and control values can be
filtered.

View or change the time filter with Filter Time Constant (Input Group). A
positive value affects only the viewed values. A negative value affects both the
viewed and control values. The filter is a single pole low pass.
