| Abstract: |
This work presents the development of a digital electromyography (EMG) device as well as the beddings and theories used in its development. The electromyography is the study of the muscular bioelectrical signal. The muscular signal is acquired through surface electrodes. It is used an analog signal conditioning circuit to prepare the signal to be converted to digital. The signal, in its digital form, is processed by the software that is executed by a DSP and the results are shown in a graphical liquid crystal display. The digital signal processing
techniques used are: FIR digtal filters and the fast Fourier transform for analysis of muscular signal specter. |
