Implementation Details
The hyperbolic secant pulse generator shapes the input digital signal to an electrical hyperbolic secant signal output. Following is the simple system in the example file Hyperbolic_Secant_Pulse_Generator.icp.
The setting table of the hyperbolic secant pulse generator is shown below, all the parameters are defined in the property table above.
Following is the output plotted by the oscilloscope with the parameters indicated in the figure.
