A sine wave generator is actually a sine wave oscillator circuit which generates an exponentially rising and falling sinusoidal waveform. The 9 simple sine wave generator circuits presented in the following article are easy to build, since they incorporate a small number of ordinary electronic components, and can be used for generating an exponentially varying […]

White Noise and Pink Noise Generator Circuit
In this post I have explained how to build a simple white noise generator circuit which can be subsequently filtered to generate the pink noise output. If you hear to the white noise or pink noise, you will find it exactly similar to the noise that we hear in FM radios in the absence of […]
7 Easy Sawtooth Waveform Generator Circuits using UJT, IC 555, and Transistors
In this post I have explained how to build 7 types of easy sawtooth generator circuits, using BJTs, UJTs, and IC 555. In a sawtooth waveform the voltage increases slowly in a slanting manner or diagonally, then as soon as it reaches the peak, the waveform voltage suddenly drops to zero. Once it drops to […]
RGB Spot Light Generator Mixer Circuit
In this RGB spotlight mixer circuit project, 3 individual spot lights are used, having red, green and blue focus light bulbs in them. The lights can be focused on walls, ceilings or floors to create interesting slow rising, slow fading red, green blue light patterns that mix and diffuse to generate interesting, additional secondary colors. […]
Digital Step Sine wave Generator Circuit
In this post I have explained how to build a simple yet accurate digital sine wave generator circuit, which is basically an oscillator circuit, enhanced to generate square waves through incrementing steps, which ultimately appears like a stepped sine waveform. By Ron Mackenzy The difference between analogue sine wave generator and digital sine wave generator […]
Sine-Cosine Waveform Generator Circuit
The circuit discussed below is designed to generate precision sine and cosine waveforms, which are perfectly identical with their dimensions, but are 90° out of phase. There are a variety of applications which often demand a couple of sinewave frequencies which are of the identical frequency, but 90° out of phase. Simply put, a sine […]
