Question

If a radio receiver amplifies all the signal frequencies equally well, it is said to have a high?

• A. Fidelity
• B. Distortion
• C. Sensibility
• D. Sensitivity
• E. Selectivity

Answer 1

The correct option is A

Fidelity

Explanation for the correct option

In the case of option (A): Fidelity

1. A radio receiver is said to have high fidelity if it amplifies each frequency of the signal equally.
2. The capacity of a receiver to faithfully reproduce all modulating frequencies is known as fidelity.
3. When all of the signal frequencies are amplified by a radio receiver equally, it is considered to have a high gain.

Explanation for the incorrect option:

In the case of option (B): Distortion

1. A signal that is "too powerful" will generate undesirable distortion. Parts of the audio signal will be lost if the audio signal level is too high for a particular component to handle. This causes the distorted rasping sound.

In the case of option (C): Sensibility

1. The capacity for feeling or receiving sensations.
2. The capacity for emotion perception and comprehension. sensibility.

In the case of option (D): Sensitivity

1. Sensitivity is the capacity of a test to identify a diseased person as positive.
2. A highly sensitive test produces fewer false-negative results and, as a result, misses fewer illness cases.

In the case option (E): Selectivity

1. Selectivity describes a radio receiver's capacity to respond solely to the radio signal it is tuned to and reject other neighboring signals.
2. Tuned circuits at the top of the detector stage carry out this task.

Hence, the correct option is (A).
