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 of the pulse train to 500ps and set the pulse width to 100ps. This means a duty cycle of 20%. 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 and compare the results to the previous case of a sinusoidal waveform. Here, too, there is a 200ps delay between the input ad 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.
