I am working on something that will require me to perform 3 different actions based on the frequeny of the input signal.
I immediately thought of using 3 band pass filters, but turns out they aren't always extremely effective.
Any ideas about how to make an efficient band-pass filter? I've checked a few of these but efficiency weren't as good as i want.
Basically, i want as high an accuracy as possible.
To give an idea, imagine you can have a signal of any frequency but you are only allowed to pass one around 700 HZ with a error rate of about %5. This sounds difficult to me, and I don't even know if this is possible.
