Question
What is the term that describes a device’s ability to amplify a signal?
Answer Options
- A) Gain
- B) Forward resistance
- C) Forward voltage drop
- D) On resistance
Correct Answer: A
Explanation
The technical term for a device’s ability to increase the strength (power, voltage, or current) of an electrical signal is Gain. Gain is a measure of how much larger the output signal is compared to the input signal.
Gain is calculated as a ratio (Output / Input) and is often expressed in decibels (\text{dB}). For example, an amplifier with a 10\text{ dB} power gain means the output power is ten times greater than the input power (T5B11).
