A Simple Digital Method for Compensation of Baseline Drift in Low-Frequency Small-Signal Waveform Measurements

Abstract

The need to measure relatively small signals mixed with drifting background levels and random noise is a common requirement in the laboratory environment. This report presents a simple device that continuously compensates for drifting baseline levels in systems where the background can be measured independently. The resulting level of automation allows the effects of random noise to be diminished through extensive signal averaging. For added flexibility, parameters such as the input voltage range and background sampling rate can be set by the user. All required hardware and software are provided and explained in detail.
