Question

If a radio receiver amplifies all the signal frequencies equally well, it is said to have high (A) fidelity (B) distortion (C) sensibility (D) sensitivity

Short answer

The correct term for a radio receiver that amplifies all signal frequencies equally well is (A) fidelity, as it represents the accurate reproduction of sound without any distortion.

Step-by-step solution

Understanding the Terms

To choose the correct term, we first need to understand what each of the given terms means: 1. Fidelity: The quality of accurately reproducing a sound or image without any distortion. 2. Distortion: The alteration or change in the original shape or characteristic of a signal or sound. 3. Sensibility: The ability to respond to or detect small changes or stimuli. 4. Sensitivity: The degree to which a device or system can detect a change in signal, input, or stimulus.

Identify the Correct Term

We need to find the term that describes a radio receiver which amplifies all signal frequencies equally well. The term fidelity represents the accurate reproduction of sound without any distortion, which fits the description provided in the exercise. So, the correct answer is: (A) fidelity
