Assume Alice is making a VolP call (voice over IP) call to Bob through PSTN. • Draw a complete diagram to show the information flow from Alice's end to Bob's end. (4 marks) This diagram should include all the devices used for Alice and Bob to communicate, and also the signal type (analog or digital) on each part. . Write a description for all devices involved and explain their functions (4 marks) Using an example to discuss what can be done from start to end and from A/D to D/A to guarantee the voice quality in a VoIP call (6 marks) . This example should start from an analog signal (human voice representation) as input, and include all factors and intermediate steps that affect quality of A/D conversion from input to the output. .
