Electrical signals, measured in volts, can be amplified by appropriate circuitry. The degree of amplification is often called the gain. Thus, an electron multiplier detector can be said to have a gain of 106, indicating that it will amplify the incoming signal one million times.

The term "gain" was found in the following pages:
