Digital Signal Processing & Communications

1.  Describe a typical application of spectrum analysis and signal processing used for signal recovery.

Download the file: “resitsignal” data set from Moodle.
The complex time-domain signal comprises of 4 corrupted noisy sine waves, sampled at 1.5MHz.

Using MATLAB and Excel, your brief is to:

2.  Analyse the signal in the frequency domain to determine the relevant component frequencies.
3.  Using  the  results  from  the  spectral  analysis, develop  and  excel  spreadsheet  to calculate  suitable  filter
coefficients to extract each sinusoidal component.
