What is the sensitivity setting on an amplifier set to produce a vertical deflection of 1 cm with an input of 10 mV?

To determine the sensitivity setting of the amplifier, it's essential to understand how sensitivity is defined in terms of the relationship between input voltage and vertical deflection on the monitor. Sensitivity is typically expressed in millivolts per millimeter (mV/mm), indicating how much vertical deflection is produced per unit of input voltage.

In this scenario, an input of 10 mV produces a vertical deflection of 1 cm, or 10 mm. To find the sensitivity setting, you can use the formula:

Sensitivity (mV/mm) = Input Voltage (mV) / Vertical Deflection (mm).

Substituting the given values:

Sensitivity = 10 mV / 10 mm = 1 mV/mm.

This shows that for every millivolt of input, the amplifier will deflect by 1 mm, confirming that the sensitivity setting should be set to 1 mV/mm for the output to match the given deflection based on the input voltage. Therefore, this correctly aligns with the definition of sensitivity in monitoring settings.
