Frequencies below 1 Hz


Hello everyone,

As I understand from the specs there‘s a low-cut filter at 1 Hz. This must be an RC circuit that does the filtering, correct?

I‘m asking because I‘m specifically interested this frequency range and would like to check if Muse is suitable for my task.



Hi Timur,

Yes, there is a low-frequency rolloff starting around 1Hz imposed by the analog electronics. You can still pick up frequencies below 1Hz, but they will be attenuated relative to frequencies in the passband. The lower the frequency below 1Hz, the greater the attenuation. How low is the frequency range you’re interested in?


Thanks for your reply Tom.

I am interested in frequencies as low as 0.1 Hz.
