    Can anyone tell me the answer or best place to find out where i could find the answer to what the effects are of applying feedback to single stage and multi stage electronic circuits for my HNC assignment?

    You couldn't quote a part of that book could you? Our library doesn't have it.

    BTW, That's exactly the same question as mine. corsa2002steve is probably someone doing my course last year.

    I guess the question is about using negative feedback, not positive feedback.
    Any tutorial about opamps would explain the benefits of negative feedback pretty well:
    1) Reducing extremely high gain to a lower useable amount.
    2) Reducing distortion.
    3) Increasing the upper frequency response.
    4) Increasing the input impedance.
    5) Reducing the output impedance.

    This is not always true, it depends on the type of amplifier (voltage, current, transresistance or transconductance).
