This formula uses 4 Variables
Variables Used
Total Current - (Measured in Ampere) - Total current is a term used in electrical engineering and physics to refer to the sum of all the electric currents flowing through a particular point in a circuit or conductor.
Incremental Signal - Incremental signal may refer to a small change in an analog signal, such as a voltage or current, that represents a small change in the input or output of a device.
Transconductance - (Measured in Siemens) - Transconductance is defined as the ratio of the change in the output current to the change in the input voltage, with the gate-source voltage held constant.
Output Resistance - (Measured in Ohm) - Output resistance refers to the resistance of an electronic circuit to the flow of current when a load is connected to its output.
STEP 1: Convert Input(s) to Base Unit
Incremental Signal: 85 --> No Conversion Required

What does common mode rejection do?

Common-mode rejection is the ability of the differential amplifier (which sits between the oscilloscope and probes as a signal-conditioning preamp) to eliminate the common-mode voltage from the output. But as signal frequencies rise, CMRR deteriorates.
