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