The scenario of a signal transmitted over a distance at the proper level is best described by maintaining signal integrity, which includes aspects such as strength and quality. When a signal is transmitted correctly, the expectation is that it will maintain its level, assuming there are no interfering factors like resistance, environmental conditions, or improper equipment.

The correct response states that a signal will decrease in signal strength or amplitude, highlighting that over distance, factors such as attenuation come into play. As the signal travels through a medium (like a cable or air), it can lose strength due to various factors including the medium's resistance and external noise, which can cause distortion and loss of clarity. This understanding is central to AV technology, where ensuring adequate signal strength is crucial for high-quality transmission and reception.

In contrast, maintaining the signal level would imply that under ideal conditions with no loss, the signal would remain consistent. However, this is rarely the case over long distances or through complex systems. Similarly, a decrease in signal frequency (which refers to the speed at which the signal oscillates) and the introduction of additional harmonics, while they can occur under specific conditions, do not happen simply by transmitting a signal over distance; they are more related to signal processing and alteration mechanisms rather than
