1.	The interval of frequencies outside which the spectrum is zero is called as ________(a) null to null bandwidth(b) normalized bandwidth(c) absolute bandwidth(d) none of the mentionedI have been asked this question in an online interview.Asked question is from Digital Communication topic in division Signals and Spectra of Digital Communications
Answer» Correct ANSWER is (c) absolute bandwidth The explanation is: The measure of frequencies outside which spectrum is ZERO is CALLED as absolute bandwidth. It is USUALLY infinite.
