Microsoft Excel isn't just for making spreadsheets; it can also perform math calculations. Scientific and mathematical formulas frequently use exponents and square roots, and you can create a function ...

After using the DFB, the square root component is stunningly trivial in its application. Just plonk it on the schematic and configure it. Obviously its internals are far more complex and you can get ...

The first time I was in school for electrical engineering (long story), I had a professor who had never worked in the industry. I was in her class and the topic of the day was measuring AC waveforms.

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 measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...
