Comparison between old value and new value

Hi Tricky,

Let me explain by an example.

-- let say new_value is incrementing or decrementing after 1 msec -- means new_value is constant for every 1 msec -- let say new_value = 4095 for 1 msec then new_value = 3998 for 1 msec then new_value = 3886 (decimal values) and so on...

Now I want to make smooth transition between 4095 to 3998 and 3998 to 3886. I dont want abrupt change of new value. that's why I store the new value to a signal then do increment or decrement to that signal while my signal is going to output having a smooth transition.
