EMG Median Frequency

Now we try to calculate the median frequency of this raw EMG data:

1. We need to use fast fourier transform.

2. Integrate the half of the data, because the other half is image of the real data.

3. Find the median value of this Integrated data.

    Here is my matlab function:

In my thesis, I analyzed EMG in time domain and frequency domain.

In time domain: the root mean square EMG

In frequency domain: Median frequency
