This is a demo shown in NIDays 2009 China which was held in Shanghai, China.
EMG (Electromyography) is similar to ECG which is very important in biosignal analysis. Surface EMG acquisition is also similar to ECG acquisition. We could use several electrodes attached on our skin and acquire the voltage changes using NI DAQ cards.
The attached is a demo VI using NI Biomedical Startup Kit Source Code version to analyze the EMG signal including RMS, Spectrogram, Median Power Frequency, Mean Power Frequency.
Requirement: You need to install NI Biomedical Startup Kit Source Code version.
