Forget about complex microcontrollers and digital integrated circuits for a while. Let’s see how to make simplified sine wave oscillator circuits using components lying around. A square wave signal is ...

The digital sine wave generator (oscillator) circuit has the advantage that only few components are needed to generate signals with high amplitude constants and variable within a very wide range of ...

A 1-kHz sine wave, labeled AC_INPUT, is The figure shows a schematic for an oscillator amplitude-control servo system. The circuit creates a closed-loop system that supplies a fixed and adjustable ...

For [Grug Huler], this was one of those “just for funsies” projects stemming from a data sheet example circuit showing a bulb-stabilized LM386 audio oscillator. He actually found it difficult ...

It uses a phase-shift oscillator with ... R3/C3 (c); and the square-wave and sine-wave outputs from this simple generator (d). A possible negative aspect of this circuit is that it requires ...

If you’ve ever fumbled through circuit ... instead of a sine wave, this video from [saisri] might just be the fix. In this walkthrough she demonstrates simulating a Colpitts oscillator using ...
