What is the minimum digital resolution requirement?

The minimum digital resolution requirement in the context of sleep study data refers to the level of detail that can be captured in the recorded signals. In various medical and technical applications, including sleep studies, higher bit depths allow for more precise representation of the analog signals collected from various physiological parameters.

A resolution of 12 bits per sample means that each sample can represent 4096 different values (2^12). This level of resolution is generally adequate for capturing the complex and nuanced data that practitioners need to analyze for sleep disorders. It provides a balance between detail and manageable data size, ensuring that important features of the signal are retained without overwhelming storage and processing requirements.

In the realm of sleep studies, accurate quantification of signals such as EEG, EOG, and EMG is crucial for diagnosis and assessment of sleep disorders. Therefore, the 12 bits per sample standard is typically employed to ensure clinical efficacy while maintaining data fidelity.
