- A.Transducer
- B.Repeater
- C.Filter
- D.Transmitter
Show correct answer & step-by-step solution
Correct answer: C — Filter
Solution
A filter is an electronic circuit that allows specific frequencies to pass while blocking others. It is commonly used to remove unwanted noise or interference from a signal.
