Experiment 5 a. Zeq = Zl + Zc + Zr; Zr = 1000, Zc = -j/wC; Zl = jwL; Z = 1000 – j/wC + jwL. Vout = Zr/Z * Vin; Vout/Vin = Zr/Z = Tv(S) = Zr/Z; W0 = 1/sqrt(LC) = 31622.7766 Damping ratio = R/2 * Sqrt(C/L) = 1.5811 Procedure 1.a) 2 Frequency, f (hz) V in V out Phase angle, q 50 100 200
Experiment 5 b) Build the circuit of Fig. 1 on a protoboard. Set the waveform generator to produce a 2 V pp sine wave (V A = 1 V), and no DC offset (V avg = 0). 3

Experiment 5 2. d) Verify that the Lissajous pattern is still centered on the oscilloscope CRT. If not, use the position controls to center the pattern on the CRT. 4
Experiment 5 e) Measure the two distances A and B in Fig. 2 using the cursor controls. The dimension A is the distance between the two intersections of the Lissajous pattern and the Y axis. B is the vertical distance between the top and the bottom of the pattern. f. Compute the phase angle θ from Eq. 1. 5

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
