(3) Suppose two digital communication systems use the same transmitter pulse function p(t). The first is an on-off system which transmits 0 or Bp(t) whereas the second is a bipolar system that transmits +Ap(t). The gain parameters A and B allow for power adjustment. If the two systems are required to achieve the same BER over the same AWGN channel, what is the power ratio A2/B2? [5 marks]
