My expeireence is that analogue and digital design are about equally
hard, but in different ways. Some people take to one, some to the
other.
Yo ucan do simple digital design (a handful of gates and flip-
flops) in
your head. You can do simple analogue design in much the same way.
When
you start making complex state machines, or using microcotnrollers,
prgrammable logic devices, analogue circuits dring 'nasty'' loads
(like a
chopper transsformer), or have many frequnce-ydependant analogue
feedback
loops, then you start neediong to use a calculator or a computer.
There is complexity and sophistication in both analog and digital
design, and there is still lots to be done in the analog world. What
I was getting at is that for problems that can be solved in both
domains, doing so in the digital domain (generally via software)
allows the designer to focus on the problem and far less so on the
physical implementation.
