EMG Processing Tools

General Processing Steps

Processing EMG signals typically follows some variation of the following steps:

1. High Pass Filter

2. Low Pass Filter

3. Rectify Data

4. Filter Noise

5. Normalize and Scale Data

It should be noted that within both this page and external literature, the term "Linear Envelope" refers to an EMG signal that has been rectified and low pass filtered.

Visual3D has a number of helpful pipeline functions (linked below) that can automate the general processing steps.

Helpful Pipeline Functions

• High Pass Filter (Remove DC Bias)
• Lowpass Filter
• Rectify
