I am looking for a function to use in a neural network.  The function
must is dependent on two variables (x and t) and must satisfy the following
criteria:

When t is high (approaches infinity) regardless of the value of x
the answer returned must be 0.5.
When t is low (approaches 0) the function must return a value of 1.0
when x is small and 0.0 when x is large.  

Can someone give me a function that can do this.  Resond by E-mail as
I'm sure this is too boring a topic for this Newsgroup.
