(Solved) : Exercise 24 Averaging Technique Useful De Noising Periodic Signals Known Period Event Lock Q31250288 . . . .

 

Exercise 24. Averaging. This technique is very useful for de-noising periodic signals (of known period) or event-locked quasi-deterministic signals when the signal and the noise are uncorrelated. Generate a 100 seconds cosine with a frequency of 5Hz, using 100 samples per second (starting fronm the instant 0.01). Each second of the signal represents one epoch. Now generate a vector of white noise, of the same length as the cosine, using the function rand (amplitude 3); Add the white noise vector to the cosine to create a noisy signal Plot the 14th epoch of the noisy signal. Use a for
