I need help with circuits - filters?

What is the difference between passband and bandpass filters?

What is the difference between stopband and bandstop filters?

I've read and looked up all the definitions I could but they all went over my head.

Can someone please explain it as simple as possible?

    ok..u have for main categories of filters..

    low pass (allow lower freq)

    high pass (allow higher freq)

    band pass (only allow a small band of freq)

    band stop (allow everything but a small band of freq)

    passband is a term used to describe the frequency portion of the filter where the signal goes through unattenuated (i.e. it isnt stopped).

    stopband is a term used to describe the frequency portion of the filter where the signal is attenuated (i.e. stopped)..

    gl with it..

    Bandpass filter is the type of the filter and passband is the frequency range the filter passes the signal through. Same, bandstop filter is the type of the filter and stopband is the frequency range the filter blocks the signal.

    I think bandstop = stopband

    and

    bandpass=passband

    The usage of the words can be different. "A bandpass filter has a passband of 500Hz". etc..
