New Circuits Page 38 Nextgr Circuit Diagram A function generator can generate different kinds of signals like sine wave, square wave or even a triangular wave at a particular frequency set by the user. The design explained in this ible uses AD9833 which can ideally generate frequencies up to 12.5 MHz as per the datasheet.
Afterwards I will then show you how to create a simple function generator, the analog and digital way. At the end I will then present you a DIY DDS function generator design which can (kind of) hold up to the commercial versions. Here you can find the schematic of the circuit as well as reference pictures of my finished perfboard
Analog Function Generator : 13 Steps (with Pictures) Circuit Diagram
The relaxation oscillator driven by IC1A is the heart of this project, but the rest of the design is what makes this a function generator. The power supply is pretty standard. The 30V 15VA center-tapped transformer generates two equal and independent 15 volt sources when the two center pins are tied to ground.
In this circuit tutorial, we're building a simple Function Generator Circuit which can generate waveforms - Sine waves, Square waves and Triangular waves. The core of this circuit is IC L8038 - which is basically a function generator chip capable of generating different waveforms. Description.

And this is how a function generator circuit can be built with an LM324 op amp chip. The function generator is pretty solid for all basic purposes, such as home use. The signals produced can be of very high quality. To see how this circuit operates in real life, see the video below.
