A Method for Designing Emg Integrator using an FPGA

摘要

Electromyography is a method for recording electrical activities of the muscle for different clinical and nonclinical tasks. For extracting more information, integrated electromyography is commonly used than the raw electromyography. This paper presents the design and implementation of integrated electromyography both in software and hardware. Software was implemented in Matlab due to easier implementation whereas hardware was designed on Field Programmable Gate Array (FPGA) due to low cost and flexibility. It can be seen that, the integrator works like a moving average window filter and a hundred-point window size is chosen in the integrator design. To verify the method, real surface electromyography data was collected and used. The mean error between software (Matlab) and hardware is 5.8288e-08 and the correlation coefficient is 1.
