A signal transmitted at the proper level will _____ over distance.

The statement that a signal transmitted at the proper level will decrease in signal strength or amplitude over distance is based on the fundamental principles of signal propagation. As a signal travels through a medium, it encounters various forms of resistance and interference that cause attenuation, meaning the signal's strength diminishes as it moves farther away from the source.

This phenomenon occurs for several reasons, such as the inherent inefficiencies in the medium through which the signal is traveling, environmental factors, and the limitations of the transmitting and receiving equipment. This is particularly relevant in scenarios involving electrical signals, sound waves, or radio frequencies. Over distance, the original amplitude of the signal decreases, impacting its clarity and integrity by the time it reaches the receiving end.

Maintaining signal strength is crucial for effective communication, which is why various techniques such as amplification or signal repeaters are often employed to counteract this natural decline in strength.
