Abstract
This report documents the design of an analog signal conditioning subsystem for a general purpose data acquisition device. The method of differential inputs is used to better control the common noise in input signals. The application flexibility of the device is maximized by combining amplifiers with selectable and wide range of gains, and variable filter cutoff frequency. Finally, test procedures and results are discussed and analysis the performance by comparing to the ideal design.
The analog signal conditioning is part of a larger collaborative effort involving several students during the 2004-2005 academic years. Therefore, the data acquisition goals and system requirements are reviewed to provide context for this work.
