• Draw and label a block diagram of a tuned radio frequency receiver.
• State two advantages of amplitude modulation over frequency modulation.
• State one application each of a.m. and f.m.

                   The expected answers were:
(a)

                                               
(b)  Advantages of amplitude modulation (A.M.) over frequency
      modulation(F.M.)
     (i)    Simple and cheaper transmitting and receiving equipment
     (ii)   Wider reception coverage area
     (iii)  More radio channels
(c) Application of A.M.
      (i)   T.V. video transmission
     (ii)   A.M. broadcasting
   

        Application of F.M.
     (i)    T.V. sound broadcasting
    (ii)    F.M. broadcasting
   (iii)    Cell phone communication
