What does the term fidelity refer to concerning receivers?

The term fidelity, in the context of receivers, specifically refers to the accuracy of signal reproduction. It describes how faithfully the receiver can reproduce the original signal it receives. High fidelity indicates that the receiver has a minimal amount of distortion and can accurately reproduce the nuances of the original signal, maintaining clarity and detail. This quality is especially important in audio and video applications where the goal is to deliver an experience that is as close to the source material as possible. Thus, when evaluating receivers, fidelity plays a crucial role in determining the quality of sound or image output.
