Question

Pre-lab Assignment P1.Simulate the circuit of Figure 1, assuming that the diode is the 1N4148 and R P1. Simulate the circuit of Figure 1, assuming that the diode is the 1N4148 and R 1 k. Also Also assume that v is a 1-kHz symmetrical triangular voltage whose peak-to-peak swing is 24 volts. Further, assume the source resistance Rs to be 50 Ω Present the waveforms of vs, vr, iD, and VD, for three cycles (periods) as Graph P1 (a). Also, present a plot of i versus vp, as Graph P1(b). Source 1 Figure 1. A voltage source driving a diode through a series resistance.

Please help me! Including the simulations, waveforms and plots ;___; Thank you so much!

Answer 1

This is the circuit used for simulation in Multisim. I used a function generator to generate triangular wave
