Question

I need help with this  Bode Plots assignment

(5 points) Follow the steps (a-c) described below for the following transfer function. Do the steps in order! 5. H50 H(s) 2000 a. On a 'blank Bode plot' grid, plot the Bode plot straight line hand sketch approximation for magnitude for the frequency range from 1000 to ω.*1000. Be sure, though, that the corner frequency aligns with an appropriate vertical line on the grid. b. On graph paper, directly below the magnitude plot, plot the Bode plot straight line hand sketch approximation for phase for the frequency range from co1000 to oe 1000. Be sure, though, that the cormer frequency aligns with an appropriate vertical line on the grid c. Generate the MATLAB bode plot of H(s) for the frequency range from o/1000 to o 1000. Keep the magnitude in dB For example, if H(s) 10 (1 + s/5), enter the following at the MATLAB prompt to generate the Bode plot for frequencies from 0. lrad/s to 1000 rad/s: (Be sure the phase is plotted in degrees!) tf(s'); H 10 (1 +s 5) bode(H, 0.1,1000))

Answer 1

aL 2000o odg 34dB . uenaj - 2000 M-milah plat :- 31 +20 ds 200 O 50 dao

matlab code:

clc;clear all;close all;
sys=tf([50],[1/2000 1])
bode(sys,{2,2*10^6})

output:

sys =
