What is the term that describes a device's ability to amplify a signal?

• A. Gain
• B. Loss
• C. Efficiency
• D. Output

Answer: (A)

The term that describes a device's ability to amplify a signal is gain. Gain is a measure of how much an amplifier increases the power, voltage, or current of a signal. It is usually expressed in decibels (dB). A higher gain indicates a greater ability to amplify the input signal, which is crucial in various applications such as radio communications, where strengthening weak signals is necessary for clear transmission and reception. In contrast, loss refers to the reduction of signal strength, efficiency measures how well a device converts input power to output power, and output signifies the final level of the signal after processing. These terms don't specifically indicate amplification like gain does. Thus, gain is the precise term for the ability to amplify a signal effectively.
