When you click on a link below, the above animation will show you the Lissajous patterns that you observed on the oscilloscope screen in lab. The function generator can supply a voltage of variable frequency and is connected to the X input of the scope. The transformer supplies a voltage of frequency 60 Hz and is connected to the Y input of the scope. When you observe the pattern traced by the electron beam on the screen, you can determine the frequency of the unknown source. For each exercise below, determine the frequency of the unknown source. Submit your answers in the form below.
A. Exercise 1
B. Exercise 2
C. Exercise 3
D. Exercise 4
E. Exercise 5
