Week 4 Lab 1 Series Resonance Lab Rep...

Part II: Bode Plotter

11. Remove the oscilloscope from the circuit and

connect the Bode plotter as shown in Figure 2.

12. Record the calculated resonant frequency from step

8 in Table 3.

13. Use the Bode Plotter to measure the resonant

frequency with C = 0.22 µF and record the value in

Table 3.

(Note: To measure the resonant frequency of a series

RLC circuit using the Bode plotter, connect the input

across the voltage source and the output across the

resistor. Run the simulation and use the cursor to find

the maximum gain. The frequency where the

maximum gain occurs will be the resonant frequency.)

14. Replace the 0.22 µF capacitor with a 470 pF

capacitor.

15. Calculate the resonant frequency with the new

capacitor value in Table 3.

16. Use the Bode Plotter to measure the resonant

frequency with C = 470 pF and record the value in

Table 3.

17. Replace the 470 pF capacitor with a 0.01 μF

capacitor.

18. Calculate and record the resonant frequency with

the new capacitor value in Table 3.

19. Use the Bode Plotter to measure the resonant

frequency with C = 0.01 µF and record the value in

Table 3.

Data Presentation & Analysis

(This instruction box is to be deleted before submission of the Lab report)

This section is the most important section of the report. Dets representations and alysis an

crucial in the engineering field. This section should include all e da collected, eg.

voltage and current readags. All resals are to be presented in both tubular and graphical

fams. All tables at have titles and all figures must have brief capions.
