ECE102 Quiz 1 – Question Pages Winter 2009 1 Student ID Name (Last, First) Write your answers on the separate answer pages; we will not look at these question pages. Question 1 (2 + 2 = 4 points): (a) Draw the Bode plot of the magnitude of H(s) . Make sure you mark appropriate points and slope of the curve, so it is fully defined. There is no partial credit for this question. (b) Draw the Bode plot of the phase of H(s) . Make sure you mark appropriate points of the curve, so it is fully defined. There is no partial credit for this question. Question 2 (1 + 1 = 2 points): Consider the Bode plot of a first order system, as shown below. (a) What is |H| at ω = 10 5 , in regular numbers (i.e. not in dB)? (b) What is |H| at ω = 5 10 3 , in regular numbers (i.e. not in dB)? Question 3 (1 + 1 + 2 = 4 points): () 5 1 j A + = jx x e e x B = ) ( (a) Find the magnitude of
