[ESDR]

Hello,
Can anyone please tell what is the working and use/working/application of op amp integrator and differentiators circuit ?

Generic questions are usually well solved googling. Trust me: lot of info available out there.

Your circuit is an integrator. It won't give the output waveforms shown (which are appropriate for a differentiator).
An integrator is often used, for example, to generate a triangle wave in pulse-width-modulation applications.
A common use for a differentiator is edge-detection of square-wave signals.

hello,
I am using sin wave and the output is -cos wave as we have formula of it sin x dx = -cos x + C
what does C mean here?
and changing value of R and C what will happen is there any formula of it?
Does the op amp is negative feed back with capacitor?
how to drawn this gain graph?

hi E,
Post your LTS asc file.

what is asc file?
where and why it is used?

Integration and differentiation are not the same thing. In post #5, your equation is for differentiation but your schematic is an integrator. This makes it very difficult to provide an answer. If you do not understand the basics of calculus, and basic opamp gain equations, then opamp circuits to implement calculus equations will not make sense.

first i am using opamp as integrator.

This is the SIM from your asc LTS image
The plot shows the frequency response you requested.

hello,
what is SIM ?

and 0dB mean there is no loss what does -ve mean here?
so, what we get from this frequency response?

SIM is this context is a LTSpice simulation of your circuit diagram.

-ve is the negative supply voltage supply to the amplifier. [ where is -ve on the diagrams???]

It would help us to help you if you tell us what you are trying to do.???

Hello,
I am working with this equation the output is cos wave which is in negative region but what does this C mean?
whatwaht is the practical application of sin integrate to -cos?
sin x dx = -cos x + C

 

[ericgibbs]

hi,
C is the Constant of Integration.
Look thru this linked example.

hello,
where is c in output wave?
and what we get fromintegrating sin wave?
what is the application of it where we can see it?

Hello all,

Just so you know, ESDR has been banned as this name is an alias for someone who has been banned many times in the past. Feel free to keep discussing for future readers, but there is no need to address the OP any further.

C can be viewed as a DC level that can exist on the integrator output at the start of the integration time.
If you integrate a sine wave, you get a cosine wave.
