A slide rule is another example. Although special-purpose, complex analog computers are built, almost all computers are digital. Digital methods provide programming flexibility. See digital computer.

At least, that’s their plan. From the 1970s onwards, digital computers became powerful enough to replace analog computers in pretty much every area, and with the increased accuracy this brought ...

But, in general, pushing a digital system to be more precise than the physical quantization or to work faster than an analog computer is very difficult. A few resistors and op-amps are cheap and ...
