# Define Pulse Mathematically

Define a time pulse using an analytical equation.

Time axis unit
Specify the unit to be used for the time axis.
Total signal duration ( ${s}_{\text{d}}$ )
The total length of the signal in the specified units.
f(t)
Analytical equation describing the input pulse, where “t” can be used as the input time variable.
Number of samples
The number of samples taken from the signal’s analytical equation.
