Abstract

An approach to signal acquisition, digitization, and processing of low-frequency physiological signals is discussed. The approach uses a chip attached to a transducer through a digital wire placed at the sensing point. The wire transmits digital information instead of an analog signal to an application-specific integrated circuit (ASIC) signal processor. This digital wire/Visp chip set produces a noise-immune signal processing system usable in a variety of biosignal processing needs. The concept is demonstrated using the Visually Evoked Potential (VEP) measurement system.<>
