All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

When plugged into the scope’s external trigger input, the circuit in Figure 1 can provide reliable, low-jitter triggering for both older and modern oscilloscopes.

When you operate the circuit from a 5V supply, the circuit's output delivers more than 2.5V rms. Although its third-order filter is inadequate for precise measurements of distortion or noise, the ...

It’s a useful technique, and as [Allen Wolke (W2AEW)] shows us, it can be accomplished with little more than a battery, a resistor, and an oscilloscope. And a little math, of course.

What you’ll learn: A Kickstarter campaign for analog circuit breadboarding closed on July 6, 2024, receiving $112,613 in funding.; There’s a new 300-page practical book on Analog Circuits and ...
