Mixed Mode Simulator:
The circuit is preprocessed. The test points and waveform markers are located in input and output of the circuit. GND net is set like reference net. The Transient Analysis parameters are set. The Transient Analysis is executed and output (o/p) waveform is seen in Waveform Viewer.
For Full Wave Rectifier with filter and without filter the output waveform might be observed in the waveform viewer.
