- Generate two signals with a length of 200, x1=sin(2pi10t)+randn1(1, 200) and x2=2sin(2pi5*t)+randn2(1, 200), where t=[0:99]/100. (randn1 and randn2 are two different random noises generated by randn.) a) Describe the main features of the autocorrelation coefficients and the cross-correlation of the two functions;b) Plot the above three coefficients in Matlab.c)Find their CSD using two methods and compare them to see if they are the same in Matlab.2.
