With examples define line coding and channel coding. Which line code is better and why? Draw the typical waveshape of modulated signal OOK, FSK and PSK for digital (2+2+6) data of 10101100. (b) A message signal is given as m(t) = sin(1000zt) and carrier signal is c(t) = 5 cos (100000xt), frequency sensitivity, k, = 200000m, and phase sensitivity, k, = 10. (a) Determine the expressions of FM signal and PM signal, (b) Find Af and for FM signal, (c) Estimate the bandwidth of FM signal. (10)
