The main purpose of an oscilloscope is to graph an electrical signal as it varies over time. Most scopes produce a two-dimensional graph with time on the x-axis and voltage on the y-axis. The voltage waveform on the screen looks as shown in the figure below. Here, the vertical resolution of the oscilloscope is set up to be 2 mV/division and the horizontal resolution is 2 ms/division. Time 1. Determine the peak-to-peak amplitude of the wave. Voltage
