= i = 4- By means of Matlab, generate 100 noisy data (observations) of a sinusoid as y; = Asin(20 ft, +0)+w; i=1,2,...,100 where A is the amplitude between 1-10, f is the frequency between 5-10 Hz., and Q is the phase between 0-2n rd., of your choosing (they may be generated by the uniform random generator of Matlab). Select wi is a zero-mean 5f A Gaussian noise whose variance is given as o? Write a Matlab code 10 which generates estimates of A, f and 0 by Newton's method for nonlinear least- squares as described in the section 9.4 of the textbook. Execute your code using the data (observations) and tabulate the results. =
