Definition: Function Generator is basically a signal generator that produces different types of waveforms at the output. It has the ability to produce waveforms such as sine wave, square wave, a triangular wave, sawtooth wave etc.

Feb 26, 2024 · An Analog function generator generates simple waveforms of varying magnitudes and frequencies that repeat over a period of time. These generators use signal generator circuit and an electronic oscillator for generation of signal.

Function Generator Block Diagram: A Function Generator Block Diagram produces different waveforms of adjustable frequency. The common output waveforms are the sine, square, triangular and sawtooth waves. The frequency may be adjusted, from a fraction of a Hertz to several hundred kHz.

Jan 17, 2025 · In this post I have explained how to build 10 simple yet useful function generator circuits using IC 4049, IC 8038, IC 741, IC 7400, transistors, UJTs etc. for generating accurate square waves, triangle waves, and sinewaves through easy switch operations.

Function Generator Block Diagram. Here, we have a block diagram for working a function generator where frequency is managed by changing the current by two supplies. These currents drive the integrator, and the generator receives multiple output waveforms.

It is very easy to understand working principle of ICL 8038 function generator using its simplified block diagram, as shown in the Fig. 5.16.1. The operation of ICL 8038 is based on charging and discharging of a grounded capacitor C, whose charging discharging rates are controlled by programmable current generators I A and I B , respectively.

Oct 18, 2021 · A function generator is generally termed as a signal generator that gives multiple kinds of output waveforms (sine, square, sawtooth, and others) based on the input signal. The device also provides the option of adjusting frequency ranges between a few Hz to some 100KHz.

Mar 6, 2025 · AM, FM, or PM modulation techniques are used for advanced function generators. It allows frequency variation over a period for testing. Here is the block diagram of function generator –. Frequency Control Network: The Frequency Control Network determines the oscillation frequency of the function generator.

An instrument which provides different types of waveforms whose frequency values can be varied and adjusted over a wide range (from a hertz to several hundred kilohertz) is referred as function generator. A function generator commonly produces sine wave, square wave, triangular wave and sawtooth wave. A pictorial view of function generator ...

Sep 20, 2024 · Carefully see the block diagram of a function generator given below. You can easily understand the working of the function generator. The above diagram describes a three-output function generator - Square Wave, Triangular Wave, and Sine Wave. Let's discuss each block of the circuit.
