Heart rate filtering #65

Closed Kirill1210 closed 3 months ago

Kirill1210 commented 3 months ago

Hello, I need to filter the heart rate signal, the sensor reads 4000 values ​​per second, I need to cut it down to 300 Hz. Will your filter be able to filter the signal, but make it beautiful, realistic and similar to a real heartbeat?

"cut it down" is just vague. As much as I like beautiful things but it won't help here. Closing it.
