DIFFERENTIAL AMPLIFIER
Differential Amplifiers - Amplify Signals, Silence Interference.

Differential Amplifier
- The name for an electrical amplifier that boosts the difference between two input frequencies is a differential amplifier.
- Usually, these differential amplifiers have two ends, one that inverts the signal and one that does not.
- The – and + signs show which of these endings inverts and which does not.
Differential Amplifier Circuit
- You can think of the differential amplifier as an analogue device with two inputs and one output.
- Below is a picture that shows how the differential amplifier circuit can be shown.
Differential Amplifier
- The difference between the two incoming levels tells the differential amplifier how much power to send out.
- In the form of an equation, this can be shown:
