You prototype in floating-point — clean, fast, forgiving — and then comes the moment of reckoning: you have to port the whole thing to fixed-point and suddenly the comfortable world of real numbers collapses into overflow, rounding...]]> Sat, 11 Apr 2026 06:08:36 +0000 AHMED SHAHEIN https://www.dsprelated.com/showarticle/1037.php During my research on digital FIR decimation filters I have been developing various Matlab scripts and functions. In which I have decided later on to consolidate it in a form of a toolbox. I have developed this toolbox to assist and automate the process of designing the multi-stage decimation filter(s). The toolbox is published as an open-source at the MathWorks web-site. My...]]> Wed, 01 Mar 2017 22:30:45 +0000 AHMED SHAHEIN
