Problem 11 (5%) Consider a random binary data sequence 0100101.... The line code is unipolar NRZ, such that each 1 is transmitted as a rectangular analog pulse with amplitude +A , and each O is transmitted as a rectangular analog pulse with amplitude 0. Assume that amplitude A=1 V, and the baud rate is 20 Mbaud (i.e., 20E6 pulses/second). (a) What is the first null bandwidth Bnull of this unipolar (NRZ) signal in MHz? (d) What is the average signal power of this unipolar (NRZ) signal? You can assume the signal is a voltage signal applied to a 1 Ohm resistor. (e) What is the average energy per bit of this unipolar (NRZ) signal? You can assume the signal is a voltage signal applied to a 1 Ohm resistor.
