b) For unipolar NRZ ASK modulation, evaluate Pe (the error probability)

b) For unipolar NRZ ASK modulation, evaluate Pe (the error probability) if V=5 volts and the noise power = 9 volts?. Evaluate erf(x) by using the table provided in the Appendix of this paper. Assume that the signalling transmits 0's and ls with equal probability. A level of V=5 volts is used for a logic 1, and a level of 0 volts is used for a logic 0. Find the value of eb/NO. Assume that the system bandwidth is 1000 Hz and the bitrate is 2 kbps. With this value of error probability (Pe), what is the probability that an 8-bit codeword is received with zero errors?
