Task:

Learning Outcomes

Upon successful completion of this laboratory exercise you will be able to:

1.Represent information as time-domain or frequency domain functions as the communication problem (amplitude modulation and demodulation) requires, and explain the equivalence between these domains.

2.Represent the operation of communication systems in time-domain or frequency-domain as the problem (amplitude modulation and demodulation) requires.

3. Discuss the basic theory and operation of analogue communication systems, specifically amplitude modulation and demodulation.

As you complete each of the laboratory exercises for this course, you will be building up capabilities towards the following:

Technical competence in basic analogue and digital communications techniques.

Designing basic communication techniques using software as the problem requires, with an understanding of the practical differences between these implementation methods.

Teamwork through conducting Lab experiments in groups.
 
Points to be addressed:

1. Explain your observations of the DSB/SC AM signal in both the time and frequency domains for these four different amplitude values (Am =
0.5, 0.8, 1 and 2). Relate your observations to the multiplication of cosines rule given above.

2. Manually calculate what the power of these DSB/SC signals are for the four different message amplitudes. From lectorial 3 the power of the
carrier, message and DSB/SC signals (respectively) were given.

3. What happens to the envelope of the modulated signal as you increase the modulation index? Particularly note what happens which  > 1.

4. What is the power of the modulated signals at these different modulation indices?
