A filter that passes frequencies between two designated cut-off freque

1.	A filter that passes frequencies between two designated cut-off frequencies and attenuates all other frequencies is called?(a) high pass filter(b) band elimination filter(c) band pass filter(d) low pass filterI had been asked this question in final exam.My question comes from Filter Networks in chapter Filters and Attenuators of Network Theory
Answer» Right answer is (c) band pass filter To explain I WOULD say: A band pass filter passes frequencies between two DESIGNATED cut-off frequencies and attenuates all other frequencies. A band pass filter has two cut-off frequencies and will have the pass band f2-f1; f1 is the lower cut-off frequency, f2 is the UPPER cut-off frequency.
