Part A: Analog Communications Review

Modulation methods within Analog Communications have evolved considerably over the last century. Produce a report outlining the key analog modulation methods.

Within your report discuss each of the major techniques. You are required to describe the operation of each technique, how to generate each technique and the

major advantages and disadvantage of each technique.

(As a guideline this should be approximately 1000 words)

Part B: Single Audio Signal Transmission

An audio signal described below is to be transmitted using a radio signal.

Vm = 2 сos(2π * 10^3) t

Propose 3 different ways to do this. Include choice of frequency, carrier frequency, bandwidth, modulation index, etc. Compare the advantages and disadvantages

of each type and suggest the most appropriate method - justify all decisions.

Part C: Multiple Audio Signal Wireless Transmission

Three audio signals described below is to be transmitted on the same wireless channel.

Signal 1 has a frequency response from 2KHz to 4KHz

Signal 2 has a frequency response from 2KHz to 4KHz

Signal 3 has a frequency response from 4KHz to 8KHz

Design a system to achieve this. You should include the frequency response at each stage. You should also justify all key decisions.
