Walking on the sidewalk, riding tricycles, bicycles, and boards all help one learn to flow with traffic and not run into people well before one ever sits behind the steering wheel of a deadly weapon. I tend to think of DSP filters as fancy optimizations on what I attempted to do using a few R's and C's out of the junk bin when I was a kid. So I prefer to start dirt simple, and only use fancier methods when a more optimal solution is desired than some simple and transparent implementation will provide. IMHO. YMMV. -- Ron N.

This is a very well known misconception. It leads to the wrong conclusions and bad solutions. Unfortunately, there is a lot of that. Although one can build a digital model of an analog filter, generally the DSP filters are NOT the simulation of the analog filters.

However it helps to know how and why a bad solution fails in order to understand why a better solution fixes those issues. More complicated solutions often have even more failure modes; and there's a lot of that as well. IMHO. YMMV. -- rhn A.T nicholson d.0.t C-o-M |
