    I am designing a pulse oximeter. I want to be able to amplify my received signal but also filter out all the unnecessary signals. My research shows that I need to focus on signals between 0.5-5Hz in terms of amplification. I will be testing in different mediums, which will affect the strength of my received signal. How can I amplify the signal using the same configuration with all mediums but still fall below the max DAQ input level (5v)?
