True. But often those limitations is what gives something character and you WANT them in the DSP solution. Audio is a good example.

Not at all, and in fact they sell quite well. Wagons in toy stores and bicycle shops more resemble carts than Mercedes's. They meet the lesser constraints using far less parts, and don't require the added costs of electronic anti-lock braking computers. IMHO. YMMV. -- rhn A.T nicholson d.0.t C-o-M |
