Square-root-calculating circuits find wide use in instrumentation and measurement systems for such tasks as calculating the rms (root-mean-square) value of an arbitrary waveform, for example. Hence, ...

If you mostly deal with DC current, you might not think much of root mean square or RMS measurements. Sure, you’ve seen meters that have “true RMS” settings, but what does it mean? If you don’t know — ...

How many times have you poked around a circuit with a digital multimeter (DMM), read an AC voltage value, then gone on your merry way? Ever wonder if your meter is giving you peak value, average value ...
