A filter which attenuates all frequencies below a designated cut-off f

1.	A filter which attenuates all frequencies below a designated cut-off frequency fc and passes all other frequencies greater than fc is called?(a) band elimination filter(b) band pass filter(c) low pass filter(d) high pass filterThe question was posed to me in my homework.I want to ask this question from Filter Networks topic in chapter Filters and Attenuators of Network Theory
Answer» CORRECT answer is (d) high pass FILTER The best I can explain: A filter is called high pass filter if ATTENUATES all frequencies below a DESIGNATED cut-off frequency fc and passes all other frequencies greater than fc. THUS the pass band of this filter is the frequency range above fc and the stop band is the frequency range below fc.
