Lab

Fourier Transform

This week’s lab is based on the application of Fourier analysis of an RL circuit in Multisim.

  1. Watch video lecture entitled “Module 8 – Steady-State RL Circuit in Multisim”.
  2. Construct Figure 18.44 in Multisim with Vi(t) set to the pulse train as below. 
  3. Run simulation to perform Fourier and Transient Analysis to measure the output voltage ‘Vc(t)’.
    1. Record the voltage ‘Vc (t)’ and the current ‘I’ through the capacitor in the table below.
    2. Take the screen capture for the measurements for ‘Vc (t)’ and line spectrum from Fourier analysis.
  4. Add 5% tolerances to resistor and inductor and repeat step 3.
Measured ‘Vc (t)’ Measured current ‘I’
Without Tolerances
With Tolerances
  1. Answer the following questions:
    1. Explain the effect of tolerance on output voltage ‘Vc (t)’.
    2. Identify the frequencies and trace the frequency spectrum for the voltage ‘Vc (t)’.
    3. How does tolerance effect the frequencies in the spectrum and the output voltage? Explain with the help of measurement results and screenshots.
  2. Create a new word document called “Lab8_StudentID.docx” with your GID substituted into the file name.
  3. Save the simulation results from step 3 and 4 along with the table and screen captures of all the measurements. Make sure to answer the questions in step 5.
  4. Upload file “Lab8_StudentID.docx”.

Final

For the circuit below, perform the following:

  1. Given an AC input voltage of Vrms = 200Vrms and a sinusoidal frequency of omega = 120pi rad/sec, determine the following:
    • V1peak (peak value of AC input voltage)
    • V1(peak-to-Vpeak )(peak to peak value of AC input voltage)
    • Frequency of input voltage V1 in Hz.
    • V2peak (peak value of AC output voltage)
    • V2(peak-to-Vpeak )(peak to peak value of AC output voltage)
    • Frequency of output voltage V2 in Hz.
  2. Construct circuit in MultiSIM using calculated values for V1.
  3. Capture a screenshot that shows V1 and V2 on an oscilloscope XSC1.
  4. Submit calculations, MultSIM screenshot and MultiSIM circuit (.ms11) file
