I have an A2D input (16 bits) currently being displayed on an excel
spreadsheet.  The bottom 4 bits are noisy.

Does anyone have experience with excel on how to get rid of these
4 bits.  (Just like 4* RRCF in .asm)

Thanks, I am struggling with excel.

Shifting right by 4 places is effectively dividing by 16.

So:

INT(A1/16) where A1 is the worksheet reference of the original number should do the trick.
