Function Generator Circuit Design

A function generator is a electronic device that can produce a variety of different waveforms.

Function generator circuit design.

Integrated function generator circuit is a central part of the design controlled via spi interface with ability to generate square sine triangle wave with frequency modulation option. It is needed for tuning resonance circuits testing audio and video equipment designing of analog filters and for many other different purposes. The different types of waveforms have different frequencies which can be generated by using the instrument as a function generator. The circuit can also easily allow for amplitude adjustment.

The proposed function generator model is based on a polynomial expansion model that uses a 10th order polynomial approximation of any of the required functions. First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency. We get ours through a potentiometer. For example one could generate a sinusoidal signal at 60hz.

Integrated circuits used to generate waveforms may also be described as function generator ics. Some of the most common waveforms produced by the function generator are the sine wave square wave triangular wave and sawtooth shapes. This instructable describes the design of function generator based on the maxims s analog integrated circuit max038. In addition to producing sine waves.

The function generator is very useful tool for the electronics freaks. These waveforms can be either repetitive or single shot. The one we will build can output square triangle or sine waveforms. Function generator is a type of instrument which is used to generate different types of waveforms like sinusoidal triangular rectangular square waveforms.

Like standard function generators the circuit allows for frequency adjustment. In this project a circuit model is proposed that can simultaneously generate many different mathematical functions.
