Strictly speaking, in a normal English conversation (not engineering) you are entirely correct, sir. > Personally I use down-sample (and up-sample for the reverse). Down-sampling is a fine term, but the word decimate is entirely correct in the DSP world...and is universally understood by people who design digital imaging systems (and any signal processing/DSP systems for that matter)...and we are talking about digital imaging systems, aren’t we? Here’s some info on decimation filters, if you’re interested: http://www.darkroom.com/MiscDocs/AN9603.pdf http://www.darkroom.com/MiscDocs/HSP43214.pdf The first document is a basic guide to digital filtering, and is quite for those who don’t know anything about digital filtering...and it does have a section on decimation and interpolation. The second document is just a hardware decimation filter...just showing that is what they call it, not a “down-sampling” filter...I just use the terms, someone else makes them up ;-)
