[TheForge] Re:analog vs digital

[Steve Smith]

Since I currently gainfully employed designing analog chips, I'll have 
to stick my oar in here.

Some things are just easier and cheaper to do analog, such as the 
megahertz video filters I've been working on lately. Note, however, that 
the signal fed to these chips comes from a digital to analog converter...

Digital does not work directly with the real world. In most cases there 
needs to be some analog piece as the interface. The more digital there 
is, the more need for analog. Cell phones are largely digital, until you 
get to the two ends of the phone, antenna and speaker. Those bits are 
analog (and the antenna end is pretty non-trivial). There are many other 
examples.
