Bio potential signal conditioning using MATLAB on electromyography signals

Abstract

In today’s world of medicine, technology plays a major role in creating solutions. Conventionally expensive equipment has been used for diagnosis involving bio signals. Such treatment is not available to most people. Most existing bio signal conditioning devices are very specific to their application, and others that are diverse require a large number of different sensors and are more expensive and cumbersome to use. There is a need for a signal conditioning circuit that is adaptable, employs digital processing and can be used to measure any of the different bio signals generated by our body with minimal modification. Use of MATLAB can greatly help researchers to analyse bio signals by giving them huge flexibility. MATLAB also has the added advantage of being able to be used on nearly all computing devices. Raw bio signal data has been captured and MATLAB has been used to mimic the various filters required to remove different types of noises that exist in a typical electromyography signal.
