| Aug 21, 2013 at 21:25 | comment | added | uniquenamehere | I now understand how headroom can prevent overflow/clipping and how one can avoid this. In the FIR filter (and other fixed-point functions) I use the products of multiplication are stored in a larger fixed-point type than the input is to prevent this problem, but it's great to have this in mind. Thanks again! | |
