Use the SimulateInstruments Generator and Instruments + Measurement Probe confered to display Res ข01uge to measure te effective DC value of the output 1. Plot two periods of ฤ(r) and tun for each of forms shown in Figure 17 on page three input wave, 2 Determine the following numenical descriptors for each type of wave form output 40 CHAPTER 1. DIODE CIRCUITS Use the following circuit components: Di-D 0.7 volt forward-biased voltage drop, ideal diode otherwise 2.2 kΩ VM-5 V, 100 Hz T- 0.01 ms) Simulation with NI Multisim Enter the circuit of Figure 1.8 on the preceding page using the 1N4148 diode model. Use the SimulateInstruments Function Generator and Simulate → Instruments → Oscilloscope instruments. Use a Simulate → Instruments-+ Measurement Probe configured to display RMS voltage to measure the effective DC value of the output o(t) 1. Plot two periods of n(t) and for each of the three input wave forms shown in Figure 1.7 on page 37 2. Determine the following numercal descriptors for each type of wave- form output o(): (a) Peak value (use a cursor measurement), and (b) Effective DC value, also known as RMS value 3. Determine the typical forward-biased diode voltage drop at the peak output voltage Additional Multisim tips for this problem: . Set distinct colors for the waveform traces to easily distinguish the input and output waveforms. . Remember that the voltage probe reports its voltage measurements with respect to ground. Because the load resistor is ungrounded, con- nect one probe to the positive terminal of o and another probe to the associated negative terminal, and then reference the positive probe to the negative probe Figure1.8 shows a diode full-wave rectifier connected to a load resistance D1 D2 Vi + Vo - D3 D4 Figure 1.8: Circuit for Problem 1.8 Analysis 1. Copy the circuit of Figure 1.8 and sketch the flow of positive current throughout the entire circuit for vi> 0. Repeat for v
