I'm not sure I understand your question. Are you asking for a definition of these terms? Butterworth data tables are usually accompanied by a schematic. If you could post one then ask a question about it there are plenty of people here who will help you.butterworth low filter
specification
passband cut off frequency
stopband- cut off frequency
passband ripple
stopband attenuation
sampling frequency
how to identify by the given specification that its low pass, high pass,band pass or band stop filter
Uh... butterworth low filter might give a hint.butterworth low filter

It will be low pass filter because Fp<Fs 500Hz<4khzAd by websave. More Info | Hide These Adsbutterworth digital filter
passband-0-500 hz
stopband-2-4 khz
passband ripple-3 db
stopband attenuation-20 db
sampling frequency-8 khz
check out this workFp = passband cut off frequency
Fs= stopband cut off frequency
case I - low pass filter
Fp<Fs
case II - high pass filter
Fs<Fp
case III - band pass filter
Fs1<Fp1 , Fp2<Fs2
case IV band stop filter
Fp1<Fs1 , Fs2< Fp2
It will be low pass filter because Fp<Fs 500Hz<4khz
I think I need stop band frequencyIf I tell you that a filter has a pass bstod that ranges from 0 Hz to 1000 Hz, do I really need to tell you anything else for you to determine what type of filter it is?
Why?I think I need stop band frequency
