1-Objective Study the sinusoidal steady state response of a resonant circuit in the phasor domain. 2-Procedure We connect the following circuit Then use the Lissajous pattern obtained on the oscilloscope to measure the phase angle θ. The X channel is connected to Vin and the Y channel to Vout. The Lissajous pattern is obtained by switching to the X-Y mode. To get θ, we apply the formula θ = sin 1 A / B We then vary the frequency and obtain the following table: Frequenc y f(Hz) Vpp of Vin (V) Vout (V) Gain (Vout/Vin) A (V) B (V) θ (°) Sign 50 2 0.07 0.035 0.068 0.068 90 + 100 2 0.14 0.07 0.135 0.135 90 + 250 2 0.341 0.1705 0.341 0.341 90 + 500 2 0.657 0.3285 0.615 0.657 69.4022 + 1000 2 1.15 0.575 0.925 1.15 53.5473 2 + 2000 2 1.7 0.85 0.916 1.73 31.9703 1 + 5000 2 2 1 0 2 0 no sign 10000 2 1.84 0.92 0.808 1.88 25.4540 6 -

### 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.
