Suppose a hexadecimal sequence AFFBD needs to be coded using the following line coding schemes: i. NRZ-I ii. Differential Manchester iii. Pseudoternary iv. Manchester Convert the stream into binary digits and encode the bits using above schemes. Draw the graphs and explain the following characteristics in relation with the obtained coded signals: i. DC Component ii. Self-Synchronization Note: Assume that the last non-zero signal level has been positive.
