Next, you will try out a rectangular pulse waveform as your voltage source. Open the property dialog of VS and change the waveform type to "Pulse". Set the period waveform [[parameters]] as specified below:  {| border="0"|-| valign="top"||-{| class="wikitable"|-! scope="row"| initial Voltage| 0|-! scope="row"| Peak Voltage| 1|-! scope="row"| Delay Time| 0|-! scope="row"| Rise Time| 1p|-! scope="row"| Fall Time| 1p|-! scope="row"| Pulse Width| 50p|-! scope="row"| Pulse Period| 500p|} The duty cycle of the pulse train to 500ps and set the pulse width to 100ps. This means a duty cycle of 20waveform is therefore 10%. Set the rise time and fall time of the pulse both to 1ps. Set the initial and peak voltages of the pulse to 0 and 1V, respectively. Run a new transient test of your circuit with the same test [[parameters]] as before and compare the results to the previous case of a sinusoidal waveform. Here, too, there is a 200ps delay between the input ad and output voltages. Due to the perfect impedance match at both the input and output, v(in) and v(out) have equal amplitudes of 0.5V. Moreover, the v(in) is simply is half-scaled replica of the source voltage.
