This article describes how to design and build an adjustable, encoder-controlled, two-range sine / square wave oscillator using the SLG47004 IC. To design a simple analog sine wave oscillator (using ...

In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of bang for the ...

Alternatively, you may want to connect its inputs and output in parallel with IC1.C to increase its drive power to the transistor test circuit. IC1.A and IC1.B together with R2, R3 and C1 form an ...

This week’s How-To comes from our newest contributor: Logan Williams. This simple guide will show you how to build a digital synthesizer that generates and manipulates square waves. Your synthesizer ...
