    :ph34r: i need to write a three page report on the integrator. every textbook i look at says the integrator performs the operation of integration.
    ok, thats fine, but i need an example!!!

    for an example u can take the integrator convets a square wave into an triangular waveform
    a sine wave into a -ve cosine wave. and so on
    ie the output voltage is the area other the input voltage curve

    hey ......even I have heard that integrator converts square waveform to triangular.........but I am not getting it........what may be the problem?

    the capacitor in the circuit is responsible for that.
    thanks haditya for the area under the curve bit. i didnt know that.

    hey girl,u can basically make ur report in three parts as follows:
    1.draw the diagram and tell what each component does.
    2.derive the equation for integrator.
    3 applications of integrator.one of the examples can be that we use integrator in FUNCTION GENERATOR to convert triangular wave of function generator into square wave.the reason for getting a triangular waveform from integrator is charging and discharging of feedback capacitor.

    hope this was of some help to you.

    hi gauri

    check on my reply #3197. its about interation and triangle wave generation :) you can use the chip TL072.

    hi,

    here's an update on the triangle wave oscillator. still using using the same circuit and adding 3 components you can now change that circuit into a sawtooth wave oscillator.

    i need 2 write a lab report bout differentiator amplifier!
    but through all my search, no details i have except differential amplifier!
