1.	In the digital communication system, signals in different frequency bands are(a) Orthogonal(b) Non orthogonal(c) Orthogonal & Non orthogonal(d) None of the mentionedThis question was posed to me by my college professor while I was bunking the class.I would like to ask this question from Signals in division Signals and Spectra of Digital Communications
Answer» The correct CHOICE is (a) Orthogonal To explain I would SAY: In digital communication system, SIGNALS from DIFFERENT frequency BANDS are orthogonal thus interference won’t occur.
