Project 3
Frequency Modulation and Detection
Objectives
In
this project, you will model an FM communications systems using the Matlab Simulink Communications Systems Toolbox and test the
system with single-tone FM (w and w/o added Gaussian noise).

Project Requirements
The objective is to observe (in time and spectral
domains) & listen as audio tones progresses along a modulation-demodulation
system, both in the presence and absence of added Gaussian noise.
Develop a Matlab Simulink
simulation of an FM system that includes a source, modulator, channel,
demodulator and sink. Test the system with single-tone audio frequency message
inputs. Note down observations in the time and spectral domains, and listen to the
audio signals and the input and output.
Bonus:
Demonstrate the Carrier-Null effect for the correct frequency-modulation
indices.
