(b) Figure Q1.1 shows a unipolar non-return-to-zero (NRZ) diagram

.

i) Find the bit sequence corresponding to the line code shown in Figure Q1.1.

ii) Draw a diagram if the line code of bipolar return-to-zero is applied to the sequence.

iii) Assume that . the bit sequence corresponding to Figure Q1.1 is a corrupted one observed at a receiver, where the Hamming code with parameter m = 3 is used at the transmitter. . only one bit in the sequence is corrupted. Find the original data sequence at the transmitter. T 5T 6T 7T
