Function Generator Circuit Diagram

As explained above the lm324 is powered by dc voltage through pins 4 and 11.

Function generator circuit diagram.

A 15 15 power supply as shown in the circuit is enough for the purpose. The frequency of the output wave form can be adjusted using r7 it must be a 100k log pot. This instrument provides different types of waveforms such as sinusoidal triangular and square waves as its output signal with a frequency range of 0 01 hz to. Function generator circuit diagram parts list.

The block diagram of a function generator is given in figure. The simple function generator two waveform it produces triangle and square waves from 1hz up to 1mhz. Function generator ranging from 0 1 hz to 20 mhz can be easily built using max038 integrated circuit chip. This project makes a useful addition to any hobbyists workbench as well.

Here is the most simple implementation of high frequency sine wave generator and you can easily modify it to generate square wave or triangle waveform. Usually function generators derive their frequency from a non sinusoidal oscillator. Function generator using op amp lm1458. That circuit is based on a lm1458 or rc4558 capable of producing sine square triangular sawtooth and pulse waveforms of high accuracy and stability.

The block diagram shows a triangular wave generator as the signal source. The breadboard circuit of the above circuit is shown below. Function generator block diagram. The circuit needs a dual power supply.

There are both high and low level outputs which may be adjusted with the level control. In this instrument the frequency is controlled by varying the magnitude of current that drives the integrator. In this instrument the frequency is controlled by varying the magnitude of the current that drives the integrator. Built around a single 8038 waveform generator ic this circuit produces sine square or triangle waves from 20hz to 200khz in four switched ranges.

Function generator circuit diagram. This instrument provides different types of waveforms such as sinusoidal triangular and square waves as its output signal with a. The components required for this circuit are lm324 op amp chip two 10kω resistors four 100kω resistors 22kω resistor 220kω resistor 1μf ceramic capacitor 33 nf ceramic. The block diagram of a function generator is given in the figure.

So the first concern is power to the circuit. So above is the function generator chip we will build. Function generator circuit diagram with lm324 op amp the lm324 is a 14 pin integrated circuit the circuit diagram of the function generator with lm324 is shown below. The function generator circuit we will build with an lm324 op amp chip is shown below.
