1. What is the likely shape of the voltage vs time graph for the internal signal used to sweep the electron beam across the screen? Explain how this signal moves the spot across the screen at a constant velocity. 2. A periodically varying voltage source produces the display on a CRO screen as shown in panel (a). Sketch the modified display in the pancls below for (b) frequency of the signal is doubled, (c) voltage of the source is doubled, (d) VOLTS/DIV of the CRO is halved. 1.
