Look into options for reducing signal noise from the breathing apparatus

[Fehings]

Summary

Our python read signal is looking much noisier than the labchart one, which is applying a filter to remove mains noise. We should at least be trying to do the same! May be other filters we can also apply to clean things further, or other things like more careful arrangement of wires and apparatus?

What needs to be done?

• [ ] Add mains noise filter to the signal (figure out how, any preset functions or just 50hz bandpass?)
• [ ] Look into other options for noise reduction

Looks like this can be done with the nidaq api! Thank you, national instruments. https://nidaqmx-python.readthedocs.io/en/latest/ai_channel.html#

Difficult to see the impact of the nidaqmx filters, worried that they may not be working properly, or we are not applying them properly? An alternative would be to look at scipy filtering, e.g. https://www.samproell.io/posts/yarppg/yarppg-live-digital-filter/
