This example shows how a simple input signal can be filtered to alter its shape. In this example, the input signal is a square “boxcar” function:
Mathematically, this can be expressed in GoldSim as follows:
If(ETime < 5 days OR ETime > 10 days, 0, 1)
The Transfer function is also a square “boxcar” function, in which any impulse is delayed for 10 days, and then spread out evenly over 5 days:
Mathematically, this can be expressed in GoldSim as follows:
If(~Lag < 10 days OR ~Lag > 15 days, 0, 0.2)
This input signal and transfer function produce the following output signal:
Note that the output signal in this case has dimensions of time (since the input signal and the transfer function were defined as being dimensionless).
