What is the calculated signal voltage if the volts per division setting is 2 and the signal moves downward 4.2 divisions?

To determine the calculated signal voltage based on the volts per division setting and the number of divisions the signal has moved downward, you need to multiply the volts per division by the number of divisions moved.

In this case, the volts per division setting is 2 volts, and the signal has moved downward by 4.2 divisions. To find the voltage, you perform the following calculation:

Voltage = Volts per division × Number of divisions

Voltage = 2 V/division × -4.2 divisions = -8.4 V

The negative sign indicates that the signal has moved downward on the oscilloscope, which corresponds to a negative voltage. Thus, the calculated signal voltage is -8.4 volts. This aligns with the understanding of how oscilloscopes display signals, where downward movement typically represents a drop in voltage relative to the baseline.
