I made this design of the activation function (sigmoid:f(x)=1/(1+exp(-x)) (capture3)
But scope displays a saturated curve instead of the positive part of the sigmoid(capture5)
I don't know where exactly the problem, if in the mathematical expression to specify the contents of the ROM(capture4)
Or in the representation of data in fixed point.
thanks in advance!
these are capture3, capture5, capture4
