Question 1:
Using MATLAB produce a composite signal of appropriate length containing a cosine wave of amplitude A at frequency f0, a sine wave of amplitude 0.5A at frequency 5h, a cosine wave of amplitude 2A at frequency 0,2f0 and a large random component, obtained using the MATLAB erandn( function.
You may select the values of fo and A yourself (but be warned I do not C X to see the same values of fo and A used by more than one student.
6) Produce a diagram of the composite signal and produce diagrams of each individual component of the signal.
(ii) Produce a diavram of the DPI of the composite signal and discuss the properties of the DR- in relation to the properties of components of the composite signal.
(iii) Design high order MAILAB slow pass 'band pass', and 'high pass' filters to Slaw, PCDIVIDUALLY, the signals at frequencies 0.2A, and 5f0 from the composite signal. import your composite signal into SIMI:LINK and apply the three filters you have designed, in turn, to the composite signal to show how effective your filter designs are at isolating the individual frequency components.
Produceplots of the frequency components that you have isolated in this way.
Compare the frequency components that you have isolated in this way with the original frequency components that you produced in (i) above.
Question 2:
"Write an essay on the role of signal processing in an engineering application of your choice. Your essaty must be fully referenced.
