A device with gain has the property of:

1. A modulation
2. B amplification
3. C attenuation
4. D oscillation

Correct answer: B — amplification. From the official ISED question bank, verified word for word.

Why

Gain means a device makes a signal stronger, which is the definition of amplification. The full explanation — and one for every question — is in Pro.
