1. The problem statement, all variables and given/known data In Figure Q1b (on the next page), two plots display samples of the continuous-time signal uct(t) = sin(2πt) and two plots display samples of the continuous-time signal vct(t) = e −t sin(2πt). For each signal, the samples in the corresponding plots are obtained with two different sampling times. Associate each of the four plots with the corresponding Z transform in the list and justify your answer: 2. Relevant equations Table of Z-Transforms 3. The attempt at a solution Ok so using considering the generic denominator of the Z transform of a sinusoid: z2+2cdz+d2 I can see that both equations 2 and 3 have a value of d=1 hence they are both undamped systems, so they are either one of (b) or (c) Then from the generic denominator equation: for (2) c=-2cos(ωT) =1.9842 = cos(ωT) = -0.9921 For (3) c=-2cos(ωT) =-1.9646 = cos(ωT) = 0.9823 Its at this point im stuck on what I need to do and how to see which one of b and c is the correct plot? Thanks for any tips!
