## sine wave into intergrator

Hi,

Have a query. How do we convert a sine wave output into a sawtooth wave?

Thanks

## convert sine wave to sawtooth

One simple solution would be first to convert it into a squarewave (bistable circuit, hard limiting) and than to integrate the signal.

## convert sine to sawtooth

triangular sawtooth wave can be gernarated by summing all even multiples of sine wave.

## saw wave into a square wave

we use integrator to get tri wave from a square wave and sine from tri, why don't try differentiator circuit like simple CR circuit similar to high pass filter, but take care of the cutting frequency of the high pass filter, this is a simple method you can use.

## convert sine wave to sawtooth wave

It hasn't been said at all, if the sine wave has fixed or variable frequency (which range) and how amplitude variations shall be reflected by the sawtooth.

## converting sawtooth to sine wave

I think, that's only one of many options - depending on th erequirements.

## convert sawtooth wave to sine wave

The input sinewave may have varying frequencies. Would there be a problem if we convert it into square wave and take integral? I tend to believe that the resulting triangular wave would have varying amplitude

## how i convert triangular wave to square wave

circuit will be in this configuration,use operational amplifire in open loop gain,it'll convert sine wave into rectanguler wave then use integrator to convert ur rectanguler wave to trianguler wave

## Re: How to convert a sine wave into a triangular wave

This circuit is connected to the 120vac power line and transfers 60Hz clock pulses to a logic circuit. The optoisolator used provides 5000 volts of isolation between the power line and the logic side of the circuit.

## Re: How to convert a sine wave into a triangular wave

if you are trying to get a triangle wave, i suggest you to use a circuit like this

it can generate triangle and pulse, with any frequency and amplitude by changing resistors and capacitor.
