If a radio receiver amplifies all the signal frequencies equally well, it is said to have high ________________?
Correct answer: D. Fidelity
- A. Sensitivity
- B. Selectivity
- C. Distortion
- D. Fidelity
Explanation
Fidelity describes how accurately a receiver reproduces the entire range of signal frequencies, so equal amplification indicates high fidelity. Selectivity instead means accepting the desired station while rejecting nearby frequencies.
