Multi channel data acquisition and signal processing using MATLAB

S. Bilawchuk, K.R. Fyfe


The Data Acquisition Toolbox in MATLAB is designed to work with several hardware devices and offer complete user control over virtually all data-acquisition parameters. Utilizing engineering computational program software such as MATLAB enables individuals to customize their multi-channel data acquisition systems and use a variety of external hardware, all for less money than off-the-shelf systems. This paper discusses some of the highlights and pitfalls with using MATLAB for digital data acquisition and signal processing.
