Transcript of "Analog Communication Mar 2013"

  1. 1. Roll No. Guru Nanak Education Trust Group of Institution Analog Communication (TEC-405) 1st Sessional Examination 2012-13 B.Tech (ECE) 2nd YearAttempt any Three Questions. Write down your Roll No on the Question paper. M.M. 30 Time: 1.00 Hr 1. (a) Why Modulation is required for transformation of the signals? (b) What do you understand by Hilbert transform and inverse Hilbert transform? Derive the expression for it. 2. What do you mean by process Communication? Draw the block diagram of communication system & explain each block in details. 3. Explain methods of SSB generation. Write its advantage with respect to DSB-SC? 4. Explain how DSB-SC modulation can be achieved by using ring modulator. Also draw required waveform. Read every Question completely and then attempt it in correct manner.
