Electroencephalography (EEG) is one of the most sensitive diagnostic tools in modern neurology. By capturing the brain’s electrical activity at the microvolt level, EEG helps clinicians diagnose epilepsy, sleep disorders, encephalopathies, brain injuries, and a wide range of neurological conditions. However, the accuracy of an EEG recording does not depend solely on electrode placement or clinical expertise—it also relies heavily on the quality of signal digitisation inside the EEG system. One of the most critical components responsible for this digitisation is the Analog-to-Digital (A/D) converter. In recent years, 24-bit A/D converters have become the gold standard in high-quality EEG systems....
