Q1 A Physical Layer transmission system uses a data coding scheme that defines a symbol as a voltage that can have one of sixteen possible values. If the system operates at a transmission rate of 1500 symbols per second, determine the data rate measured in: (a) Baud (2 marks) (b) Bits per second (4 marks) (c) Draw a diagram showing how a logic 1 and a logic 0 is represented by using Manchester encoding. Make sure the diagram is labelled correctly.

Q2 HDLC (High-level Data Link Control) is a group of protocols for transmitting data nodes. In HDLC, each message starts and ends with the unique flag sequence of 01111110. To prevent this flag sequence from occurring in other parts of the message, a process known as zero bit insertion, or bit stuffing is used. Draw a diagram to show how zero bit insertion is used when transmitting the following 5 message data bytes. 01110011 11110111 01111110 01001101 11111100
