Bits can be sent over guided and unguided media as analog signal by __

1.	Bits can be sent over guided and unguided media as analog signal by ___________(a) digital modulation(b) amplitude modulation(c) frequency modulation(d) phase modulationThe question was posed to me in an internship interview.The query is from Physical Layer topic in chapter OSI Model of Computer Network
Answer» The correct ANSWER is (a) digital MODULATION The EXPLANATION is: In analog modulation, digital low frequency baseband signal (digital bit stream) is TRANSMITTED over a higher frequency. Whereas in digital modulation the only difference is that the base band signal is of discrete amplitude level. The bits are REPRESENTED by only two frequency levels, one for high and one for low.
