Absolutely, an analog scope is fine for digital signals.  IMHO a low end
analog scope would be far more useful than a low end digital scope, but
that's my opinion.  I have not used digital scopes extensively, but from
what I understand a cheaper DSO might nt have a hgh enough sample rate to
catch very short glitches.  You won't see a one-time glitch on an analog
scope either, but you won't miss any detail.
