Ambrish, I am really confused on how the parameter taps is used in the Statistical and Time domain flow. In some places it is a coefficient between -1 and 1, and some places it is an increment and decrement. And some places there seems to be an relationships of 1/32 between increments and coefficients. Can you clarify this please.
