Assignment #14 ECSE-2410 Signals & Systems - Spring 2007 Fri 03/23/07 1(30). Consider the transfer function () ( ) () ω j + j + j + j = H 50 100 1 10 10 2 . Using Bode approximations , find the values for the indicated operations: (a) (b) (c) (d) . | H(5) | | H(15) | | 0) H( | 6 H(10) Find (e) | ) H( | as , and (f) ) H( as . 2 (30). To see the effects of different poles and zeros i.e., break frequencies, sketch the straight-line Bode plots (magnitude and phase) AND the pole-zero plots for each case below, where the transfer function has the form b s + 1 a s + 1 K = H(s) . a.)

Draw the asymptotic plot on top of the actual (exact) plot obtained from MATLAB. Include your name in the title of the plot. Clearly label your plots with the break frequencies and the slopes of the asymptotes (decibels/decade or degrees/decade). Compare your straight-line Bode plot with the actual plot obtained from MATLAB. Assign#14. p.1 4(15).
