    equivalent noise bandwidth

    all:

    what is the RMS bandwidth, or equivalent noise bandwidth?

    There are some express for it.

    [[The noise bandwidth of a frequency response H(f), or RMS bandwidth, is the cutoff frequency at which a box-shaped frequency response would pass the same amount of white noise energy as H(f).]]

    I cannot understand it. who can give me some details for it?

    rms bandwidth

    The area under ideal box-shaped frequency response curve should be equal with the area under the RMS bandwidth of your real response curve.

    what is the RMS bandwidth, or equivalent noise bandwidth?

    Or you can read Chapter 4 in Johns&Martin book which is available at this site.
