Paper Abstract

An AC-coupled amplifier system in biomedical instrumentation suffers from baseline variations which cause problems for the accurate measurement of signal amplitude,which may even be and even out of the measuring range of the system. A DC-servo baseline restorer has been designed to restore the baseline of a DC-coupled signal to a zero DC level. This enables a DC-coupled amplifier to be used in biomedical measurement systems, such as blood cell-sizing and ECG.
