For example one could generate a sinusoidal signal at 60hz.
Op amp function generator circuit.
The basic functions performed are as follows.
The operational amplifier based square waveform generator is a simple circuit that is widely used in function generators.
The breadboard circuit of the above circuit is shown below.
The two opamps inside lm1458 has a common bias network power supply line and are independent of each other in operation.

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.
We have already designed sine wave generator circuit square wave generator circuit and sawtooth wave generator circuit.
The next two were used as integrators to give output as triangle and sine wave respectively.
As its name implies the op amp integrator is an operational amplifier circuit that performs the mathematical operation of integration that is we can cause the output to respond to changes in the input voltage over time as the op amp integrator produces an output voltage which is proportional to the integral of the input voltage.
Function generators are primarily used for working with analog circuits related pulse generators are primarily used for working with digital circuits.
Capacitor connected to orange colour in fig op amp is while charging it used to generate fixe wave form periods and generate a square wave the left side circuit acts as a astable multi vibrator and the right side circuit acts as a integrator.
Simple function generator by lm566.
You can use it to test the inner workings of audio amplifiers find the characteristic of op amps and diodes make funky noises the list of.
Diy function generator circuit using quad op amp.
The function generator circuit we will build with an lm324 op amp chip is shown below.
Initial op amp was used for square wave generation.
Lm1458 simple function generator.
This circuit design might come in handy for those who want to build a efficient fg of their own.
First a function generator also called a tone generator is an electronic device that can output a specific waveform at a set frequency.
The circuit for square wave generator is designed using 741 op amp.
Op amp triangular wave generator function generator or waveform generator is an integral part of electronics and used to produce various kinds of waveforms like a sine wave square wave sawtooth wave etc.
A simple function generator circuit using lm1458 is known here.
Fg s are quite expensive in nature and not many could afford one for their experimentation and learning.
