Most amateur SDR use a PC and not a dedicated Digital Signal Processor. I made a classification of SDR architectures explained here : http://f4dan.free.fr/sdr_class_eng.html If you look the project list here : http://f4dan.free.fr/sdr_eng.html, you will see that most SDR are of type ***-H-**, meaning that digital channel selection is made on a host PC. Few project use dedicated DSP : this is example the cas e of F1OAT (http://www.teaser.fr/%7Efrible/) and DSP-10 (http://www.proaxis.com/%7Eboblark/dsp10.htm) > And i think there is a confusion over, whether DSP > stands for Digital > signal processing or digital signal processor. > I think it means both, depending on context !
