For some functions, such as the absolute value function, the values are continuous, but there is a point (or points) where the derivative does not exist because the slope on the right is different from the slope on the left.  I can use this criteria to determine whether a function is 'smooth'.  How can I decide whether a digitized signal is smooth??

There is no such thing as a smooth digitized signal. The more filters you put on it, the less choppy it gets, and it gets less choppy as you increase the bandwidth of it. However, because a digitized signal is still restricted to a discrete set (8bit=0-256, 16bit=0-65536), derivatives cannot apply to it, since it's a set of points.
