When viewed through an oscilloscope, alternating current should look like a sine wave alternating smoothly between negative and positive polarity. However, the AC produced by most inexpensive car ...

Welcome back to this week’s installment of Scope Noob where I’m sharing my experiences learning to use my first oscilloscope ... again probing my incoming AC waveform to make sure that ...

After years of wanting one (and pushing off projects because I didn’t have one) I finally bought an oscilloscope ... you could call it a built-in sine wave source. I sometimes take criticism ...

Tom Werner / Getty Images A sine wave is a geometric waveform that oscillates (moves up, down, or side-to-side) periodically and is defined by the function y = sin x. In other words, it is an s ...

The circuit creates a closed-loop system that supplies a fixed and adjustable peak-to-peak amplitude ac signal centered around 0 V. A 1-kHz sine wave, labeled AC_INPUT, is The figure shows a ...
