Synchronous detection is a measurement method where a stimulus is modulated with some frequency and the response is demodulated to bring the signal back down to base band. Performed when a dc stimulus ...

In the first part of this series we discussed pedal effect circuit design and in the second part we looked at a distortion pedal circuit with low power and soft clipping. Now we will discuss a rather ...

An oscilloscope's track and trend features add two measurement-based math functions that you can use to gain insight into measurements. Trend is a plot of measured parameter values in the order the ...
