The Differential Lag component serves as a first order high pass filter and is sometimes known as a 'washout' function, a 'change' function, or a 'forgetting' function. The output can be reset to the user specified value at any instant.
The solution method for this function is based on the value of the time constant T as follows:
If T = 0:
The output is then,
