Am I correct, or am I way off base? > = I think you need to start with the AD converter. Determine how fast it has = to = be and how many bits it has to have. Since you are sampling two signals (if= I = understand you correctly) you also have to take that into consideration. = I don't know anything about the DSPICs but it might have better (faster) AD = converters than the regular PICs and that might be reason enough to go for = a = DSPIC. /Ruben =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D Ruben J=F6nsson AB Liros Electronic Box 9124, 200 39 Malm=F6, Sweden TEL INT +46 40142078 FAX INT +46 40947388 ruben@pp.sbbs.se =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
