    HI~! GUyz

    I'm from Korea, I studied electronic engineering,, I'm a girl.,.

    It is report of my experiment,,

    My experiment is about the integrator and diffrentiator
    I want to help my question,,

    Q. What effect would you expect on the output of the integrator in Figure if the frequency used had been 100 Hz instead of 1kHz?

    I attached to my figure in below..

    I think that when the frequecy is decreased, integrator output would be low pass filter frequency,,

    Anybody, explain to me.. I want to know exactly,,

    Hint: does the integrating capacitor have the ability to soak up 10 times the charge? If not, what will happen?

    Actually, the output voltage will be GREATER. The capacitor will have more time between cycles to charge up. (Remember the RC time constant).
