A change in sensitivity produces a change in the?

A change in sensitivity in the context of sleep technician practices typically refers to how responsive a sensor or measurement device is to incoming signals. When sensitivity changes, it directly impacts the amplitude of the wave being detected. Increased sensitivity amplifies the signal, resulting in a greater height of the wave, which represents a stronger or more pronounced response to the stimulus.

Understanding the nature of waves, height (or amplitude) is a fundamental characteristic that indicates the strength of the signal being measured. If sensitivity is increased, even small changes in the incoming signal can produce larger deviations in the height of the resulting wave. Conversely, if sensitivity is reduced, the same incoming signal might produce a smaller wave height, showing less change in response.

Voltage, frequency, and color are characteristics of a signal that may not be directly related to sensitivity adjustments in the same way. Voltage relates more to the absolute strength of a signal rather than how much it responds to changes in amplitude or the sensitivity settings of the equipment. Frequency indicates the rate of oscillation and is not directly controlled by sensitivity. Color, typically related to light waves, does not apply in the same context as sensitivity changes within the realm of sleep studies. Therefore, height of the wave is the correct understanding in relation to changes in
