[Function]
A function to programmatically realize CR filtering effect by performing a primary delay operation for PV of the input.
Filter effect will be set through time constant.
(Time constant is a time that was spent before PV to reach up to approximately 60% when the input has changed in a
step-by-step manner)
※The purposes of PV filter are the following:
① The effect of the electrical noise that was applied to the input can be minimized by eliminating the high-frequency
noise.
② The response against sudden change of the input can be delayed.
