question 3 matlab

Ma Date of allotment: - February 16, 2021 (TUESDAY) Date of submission: - February 23, 2021 (TUESDAY) Copied assignments will be given zero. Make the program in software and take snapshot of program and result, graph and paste assignment. Get your work handwritten on A4 sheets only. No submission will be consider after due date. Implement the problems in MATLAB. Q1: An LTI system is described by the difference equation: y(n) = 2x(n)+0.3x(n-1)+0.5x(n - 2) - 0.7y(n 1) - 0.9y(n 2) Determine the Direct-form I and Direct-form II realizations structure of the system. Q2: What is the difference between FIR and IIR Systems? Q3: Find the linear convolution of the sequences x (n) and h (n) using DFT. x(n) = [1, 0, 2], h(n) = [1, -1] Q4: Find circular convolution by using both graphical and matrix method? Also, ve results with programs. x(n) = [1 3 4 1] h(n) = [24] Q5: a) Find the DFT of the sequence: x(n) =[1, 2, 3. 1] b) Find the IDFT of the sequence: X(k)= [6-j, 2, 3+j, 4] Also, verify the results with programs. = s
