For Those with Digital Questions..........
 

My mathematician/design engineer friend suggests this tome to for those who might want to dig below the surface in understanding digital electronics and their applications in audio. I stopped reading stuff like this when I retired 10yr ago and even try to avoid thinking about it (I'm a tube/analog type of guy). But he can't seem to help himself.

He sent some additional info. If interested, send me a PM.
