I need help with this MATLAB exercise.
The given system is y[n] - (3/10)y[n-1] - (1/10)y[n-2] = 2x[n]
The input x[n] is 2cos(2*pi*n/6)(u[n] - u[n-10])
Don't have to answer part 2 of the question.
Hello,
Please find the answer
attached below. If the answer has helped you please give a
thumbs up rating. Thank you and have a nice
day!
********** Matlab code for plotting the convolution *********
b =
2;
%filter coefficients
a = [1 -0.3 -0.1];
[h,n] = impz(b,a); % impulse response
x = 2*cos(2*pi*n/6).*double(n<10);
y = conv(h,x); % convolution
stem(y);
grid;
xlabel('N');
ylabel('Y');

************** End of file ************
Output:
The systemk is asymptotically stable since the impulse response, as well as the convoluted response both are damped responses.

CONVOLUTION - Questions 4 and 5 4. Consider an LTI system with an impulse response h(n) = [1 2 1] for 0 <n<2. If the input to the system is x(n) = u(n)-un-2) where u(n) is the unit-step, calculate the output of the system y(n) analytically. Check your answer using the "conv" function in MATLAB. 5.

Please provide MATLAB code and plot, about system response. Will thumbs up. Thanks. Question 1: MATLAB contains a built-in function called conv which performs the convolution of two vectors: >> help conv conv Convolution and polynomial multiplication. C - conv(A, B) convolves vectors A and B. The resulting vector is length MAX ([LENGTH (A)+LENGTH (B)-1, LENGTH(A),LENGTH (B) 1) If A and B are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials. Compute the system response...
