SUBJECT : DATA COMMUNICATION AND COMPUTER NETWORKING

3. a) A digital data stream 0010110101 is passing through a communication system. As we know data stream will be converted to signal using various schemes. Draw the signal of a given bit stream using NRZ-I, Manchester and Psuedoternary scheme. (6 Marks) b) Draw three sine waves with the same amplitude and frequency using phases ( 90^{circ}, 180^{circ} ) and ( 270^{circ} ). (4 Marks) [Total: 10 Marks]
