    HI ,

    I want to measure a small squre pulse signal (amplitude ~ 200 mV and
    frequency in between 0.1 Hz and 2 kHz) across a small resistance in a
    circuit. I want to make instrumental amplifier. Can some one tell me
    how to select the right OPamp for this. It is not necessary to select
    the gain at first, but I can cascade couple of them.
    I need explanations for such as CMMR , Gain , frequency responce etc

    Thank you,
    Pubudu

    Your best bet would be to go back and review this year's lessons in the
    textbook.

    Maybe borrow some notes from someone who actually listened at the lectures.

    Good Luck!
