there's a good approximation for tanh that can be made using just a couple of simple arithmetic objects:
formula is: tanh(x) ~= x*(27+x*x) / (27+9*x*x) it's close enough for every application i've ever come across, it's cheap cos it only uses simple arithmetic, and it doesn't degrade the resolution of your signal like a table lookup does.
