QUIZ 1 EENG2620 due 2/10/2022 @ 11:59 PM. Submit under quiz 2 1. Example of DT convolution of a system h(n) with an input x(n) x = [1 2 0 0 -3]; h = [3 2]; Step 1: invert one the two, for instance h=[2 3] Step 2: shift h along x and do the sum-of-products x = [1 2 0 0 -3]; h = [2 3]; y1=3x1=3 keep shifting to the right x = [1 2 0 0 -3]; h = [2 3]; y2=1x2+3x2=8 keep shifting to the right x = [1 2 0 0 -3]; h = [2 3]; y3=2x2+3x0=4 keep shifting to the right x = [1 2 0 0 -3]; h = [2 3]; y4=2x0+3x0=0 keep shifting to the right x = [1 2 0 0 -3]; h = [2 3]; y5=0x2+3x-3=-9 keep shifting to the right x = [1 2 0 0 -3]; h = [2 3]; y6=-3x2=-6 …now you see why it is called convolution Use the MATLAB code below to verify the answer above: x = [1 2 0 0 -3]; h = [3 2]; y = conv(x,h)
Problem 1: Try the convolution of these two signal/system, x = [-1 0 2 5 0 -3 4 7]; h = [-1 -2]; then verify your answer using MATLAB. No need to show the hand results. Copy and paste the results from MATLAB here: 2. Example of CT convolution of a system h(t) with an input x(t) Go to https://lpsa.swarthmore.edu/Convolution/CI.html 1. Set the parameters of the convolution as shown below. Move the slider to perform convolution. Observe the output y(t).
