What is a Function Generator?

Function Generator as the name suggests is an electronic equipment that allows us to generate waveforms corresponding to different functions and also gives us the control over the properties of this function generated by it. By properties, we mean that once a functional waveform has been generated, we can control how much is its amplitude, what is the frequency after which it repeats . Depending on the trigger given the signal generated can be repetitive or not. Function Generator is known to be versatile because of its ability to produce various waveforms with wide frequency range. This is the formal definition of Function Generator

A Function Generator is a scientific device that can generate a variety of different waveforms with a wide range of frequencies.

Function Generator

In the field of electronics engineering, scientists and researchers often require signals that can be fed as an input to various devices which can later test their devices on these signals. Devices like modulators, filters, and analog-to-digital convertors require some input signals and other signals for testing. You will wonder what researchers do to get these signals. The answer to this is Function Generator. These are the devices that can generate different types of signals each representing different functions. These can be trigonometric signals, square functions, or any other necessary function. In this article we will see what is a function generator, we will also see the block diagram of a function generator and understand its working through it.
