STC networks can be classified into two categories: low-pass (LP) and high-pass (HP). Then which of the following is true?(a) HP network passes dc and low frequencies and attenuate high frequency and opposite for LP network(b) LP network passes dc and low frequencies and attenuate high frequency and opposite for HP network(c) HP network passes dc and high frequencies and attenuate low frequency and opposite for LP network(d) LP network passes low frequencies only and attenuate high frequency and opposite for HP networkI got this question during an internship interview.The above asked question is from Frequency Response of Amplifier topic in portion Signals and Amplifiers of Electronic Devices & Circuits

Answer» RIGHT option is (b) LP network passes dc and low FREQUENCIES and attenuate HIGH FREQUENCY and opposite for HP network

To explain I would say: By definition a LP network allows dc current (or low frequency current) and an LP network does the opposite, that is, allows high frequency AC current.
