3. The equation: Vam (t) = 10 sin (2ft) + 2.5 cos 300nt-2.5 cos 2000nt The signal is applied to a 5092 load. I. Determine the modulation coefficient in percentage II. Sketch the frequency spectrum by using Bessel function table by use the value of modulation index from the equation III. Assume transmission have transmit five channels with probability 0.1, 0.35, 0.05, 0.2 and 0.3. By using Shannon Fano coding, determine the code word and efficiency for the channel. IV. By using code word in (x), sketch the line coding for polar non return to zero, return to zero inverted and Manchester IEEE. [21 marks]
