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...

Tutorial 1: Raw EMG Signal Acquisition.

By | Uncategorized | 3 Comments
Raw Electromyography Signals EMG signals generally lie in the range of 20-150 Hz depending on the muscle unit selected and the electrodes – but they are extremely noisy. To reduce this noise, we have used three surface electrodes, namely E1, E2 and E3. E1 and E2 are used to record muscle activity from...
