Hello
How does the emg data filter which recoreded with sampling frequency of 250 Hz?
The data were recorded from forehead muscles in static and normal face position.
The time of recording is 5 minutes and three emg electrode were used.
Participants were male soccer players with 19 to 25 years old.
What type of board are you going to use? I recommend using this type of ECG amplifier

It contains hardware filters for both low and high frequencies. You can additionally add software digital filters, according to your requirements.
Thank you Vladimir Kubov
Motshakeram from you.
But we use Medina teb company amplifier as may see in the below address:

The question is how we report the emg data that recorded with sampling frequency of 250 hertz?
Look here:
https://en.wikipedia.org/wiki/Electromyography
https://en.wikipedia.org/wiki/Electrocardiography
https://en.wikipedia.org/wiki/Electroencephalography
EMG is low-frequency signal bursts with high-frequency noise-like filling. Most often, the amplitude of the bursts and the repetition rate are analyzed. And the high-frequency noise-like filling is probably not very informative.
But in EEG, they conduct a spectral analysis of a noise-like signal with a slowly changing envelope in different frequency filters, which are associated with specific rhythms.
In ECG, little attention is paid to frequency spectra, but the period and shape of the signal are analyzed.
Unfortunately, I can't read the source
