If probability distribution function is flat like a rectangular signal then probability density function which is differentiation of probability distribution function will have positive and negative impulses, but probability density function cannot be negative. . whats wrong in this . . . Can't probability distribution functio be flat ?

Sometimes, "probability distribution function" is used as "probability density function".

The differentiated function is not a probability.

Probability density function
neither is the rectangular function a distribution function. a distribution function must be an increasing function (so that the derivative, which is the p.d.f., is always nonnegative).
