Which device is used to reduce the strength of a signal in a communication channel?
- A.Amplifier
- B.Transducer
- C.Attenuator
- D.Repeater
Show correct answer & step-by-step solution
Correct answer: C — Attenuator
Solution
An attenuator is a passive electronic component that reduces the power of a signal without appreciably distorting its waveform. It is the opposite of an amplifier.
