Selecting the highest value from a stream of five different channels and determining its source
Jul 16 2017 | 9:25 am
Hello,
I need to detect the highest value coming in from different sensors which I can do, but then I have to know where this value came from in order to know where to send it to. I am using the Axion Muse headband and receiving simultaneously five different values for the five different brainwaves, delta, theta, alpha, beta, and gamma. By comparing their values I can tell which value is the highest but my problem is then how to determine to which brainwave the result belongs?
For example I can compare two numbers like that: [if $f1 > $f2 then $f1 else $f2], then two other numbers, and then the last two results to get the highest value, but in the process I don't know anymore to which brainwave the result belongs ?
Any suggestions?
