Hi..

How can the integrator convert the square wave to triangle wave? or triangle wave to sine wave? Can you give a complete explanation? Thanks..:)
 

The waveform isn't a real sine, it's comprised of parabolic arcs. You can refer to the mathematical definition of integral to see why.
 

Hi,

I mean, can you explain the operation of the integrator. From the input to the output in a square input, triangle input and the "parabolic arc" input.. Thanks.. :)

Please remember the voltage-current relationship of a capacitor in the time domain (it`s an integrating operation).
 

Dear Friends
Hi
I agree with FvM. but you can give your imagine sine wave to the filter and then take a real wave form(sine wave).
And about miller integrator with capacitor: Vo = 1/RC *integral of vi dt. if the capacitor be in the constant current source
, It's action can being as an integrator . if you want more , i can describe it with it's equations.
