I-Objective: The purpose of this experiment is to examine the sinusoidal steady-state response of a resonant circuit in the phasor domain. II-Procedure: 1. Prepare a data table and build the circuit a. Prepare four columns’ table, labeled frequency, V in , V out and phase angle θ. b. Build the circuit above. Set the function generator to produce a 2 Vpp sine wave and 0 DC offset. 2. The Lissajous Pattern: used to measure the phase angle θ between two sinusoids of the same frequency. The channel I (X channel) is connected to the input voltage (V in ), and channel II (y channel) is connected to the output voltage (V out ). The oscilloscope should be set to X-Y mode to obtain the Lissajous Pattern. This help us to calculate the phase angle θ, θ=sin -1 (A/B). A: is the distance between the intersections of the Lissajous pattern and the Y-axis. B is the vertical distance between the top and the bottom of the pattern.

### 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.
