Q1: Choose one of the choices indicated in the parenthesis such as the following sentences have the correct answer: 1) The process of combining signals that are at slightly different frequencies to allow transmission over a single medium is called frequency (shifting, division, modulation, multiplexing). (0%,50%,33.3%,66.6%) of the total transmitted 2) In AM, 100% modulation indicates that power is in the sidebands. 3) A SSB is not used in broadcasting purposes since be generated ,it is difficult to be detected ,it requires less bandwidth). 4) Which of the following is not the advantage of FM over AM? (FM can be made relatively immune from noise, Amplitude of modulated wave is constant, more bands are required, none of these). 5)The extra carrier signal added to the modulated signal in order to achieve synchronous demodulation at the receiver is called (IF carrier, Composite carrier, Subcarrier, Pilot carrier). (low frequency, high frequency, both low and high (it requires less power, it is difficult to 6)Pre emphasis is used to amplify_ frequencies, none of these). 7) For FM wave carrier, modulating frequency is 10 KHz and bandwidth is 2MHz if the modulating
