Laplace Transform and Analysis in S-Domain
This week's lab is based on the application of circuit analysis techniques to a capacitive circuit with Multisim. You will learn to utilize Multisim to perform the mesh analysis.
- Watch video entitled "Week 6 - Oscillator Circuits in Multisim"
- Design a Wein bridge Oscillator in Figure 15.39 in Multisim to generate a sinusoidal signal at frequency of 300Hz. Consider a capacitor of 1uF, resistor R = 5950?, R1 = 3?, Rf = 6.05? for the oscillator circuit.
- Determine output voltage 'Vo' and run the simulation to plot the output of the oscillations at frequency of 300 Hz using an oscilloscope.
- Increase the frequency to 500Hz, 800Hz and 1000Hz and plot the output of the oscillator at these multiple frequencies.
- Take the screen capture of the oscilloscope readings for all the frequencies.
- Answer the following questions:
- What is the requirement to generate oscillation in the circuit? Is the circuit stable or unstable?
- What do you observe in the oscillations when the frequency is increased?
- With increased frequency, did you observe the oscillations? If not what did you adjust to observe the oscillations?
- Explore different practical applications of oscillator circuits and explain.
- Create a new word document called "Lab6_StudentID.docx" with your GID substituted into the file name.
- Save the simulation results from step 2 along with the measurements and screen captures. Make sure to answer the questions in step 6.
- Upload file "Lab6_StudentID".
