## Integrator - -Square Wave to Triangle Wave and Triangle Wave to Sine Wave

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.. :)

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.

Regards
