1.	For telegraphy pulse code modulation (PCM) is widely used.(a) True(b) FalseThis question was addressed to me in an internship interview.Enquiry is from Frequency Discrimination Method in portion SSB Modulation of Analog Communications
Answer» Right option is (b) False Explanation: FSK (Frequency SHIFT Keying) is a method used to transmit binary data in form of digital SIGNALS. It is MAINLY used for telegraphy. In telegraphy, a modem is used to convert binary data to FSK and vice-versa, for the communication between computers and over TELEPHONE LINES.
