1) What is the purpose of the deflection plates in the CRT?

2) How does the oscilloscope produce a stationary pattern of an AC voltage signal?

3) What is a Lissajous figure? Be sure to (a) discuss how one is made, and (b) sketch an example of one.

4) A sinusoidal voltage is displayed on an oscilloscope screen. The separation on the screen between two adjacent peaks is 3.5 divisions, and you notice that the sweep speed is set to 1 ms per division. What is the frequency of the sinusoidal voltage?

5) The peak voltage of the source from problem 4 is 12 V. You notice that the sensitivity setting on the oscilloscope is 5 V per division. How many divisions, peak to peak, will the voltage span on the oscilloscope screen?
