Tutorial 6: Keyboard Emulation

By | Uncategorized | No Comments
The project “Pschyo-physiological training approach to amputee rehabilitation” main aim was to create a human-machine interface using EMG signals for rehab process. We used the processed EMG to act as key stroke for a game application.   EMG detection:- First we will discuss the methods we used to detect EMG...

Tutorial 5: Sample Based Processing-2

By | Uncategorized | No Comments
In the previous post we discussed about Band-passing EMG signal using SigmaStudio. In the project “Pschyo-physiological training approach to amputee rehabilitation” we used the RMS value of the filtered signal for detect EMG activation. Here we will discuss the algorithm used for EMG detection. RMS calculation The RMS value of...

Tutorial 3: Sample Based Processing

By | Uncategorized | No Comments
In sample-based processing, blocks process signals one sample at a time. Each element of the input signal represents one sample in a distinct channel. For example in figure 1 from a sample-based processing perspective, the following 3-by-2 matrix contains the first sample in each of six independent channels. Fig 1...

Blog 2: Rectification Vs. Dc Shifting.

By | Uncategorized | No Comments
All our experiments were performed with reference electrode shorted to ground (0V) of the instrumentation amplifier, hence the acquired raw EMG signal has both negative and positive peaks. Please refer here for more details about raw EMG acquisition. The band passed signal is used as an input to a microcontroller...
