Analog Computers – Part 2: No clock. No CPU. No mercy - the analog revival
Hope you had some fun tinkering with that simple analog temperature comparator from the previous part. That circuit was stripped down to the bone – a classic “how to even do linear signal processing with op-amps” example. But the world doesn’t end at a comparator. You can build 4–20 mA → voltage converters, voltage → frequency, even a basic PID… But today let’s zero in on what used to actually be called an analog process computer. ...
