What is the role of the phosphor screen in a CRO?

• To generate the electron beam

• To deflect the electron beam

• To display the visual representation of the signal

• To amplify the signal

How is the amplitude of a signal typically measured on a CRO?

• By counting the number of waves

• By measuring the vertical displacement on the screen

• By adjusting the time base

• By changing the frequency

Which of the following adjustments would you make to increase the brightness of the trace on a CRO?
