Bode plot axes
Is the x-axis of a Bode plot supposed to be angular frequency omega or just the frequency f? The y-axis is in dB. Thanks!

Usually when I draw it on paper, I have it in angular frequency [rads/sec] (log scaled). The y axis is 20 log (|H(jw)|) [dB].

hi, i would like know how to set the range on the axis? for an example i want to plot a nyquist plot with the range of x-axis is from -0.08 to 0.02 and the range of y-axis is from -0.2 to 0.2. (with the system G =(5s + 200)/((s)*(s^2 +4s + 10)*(s^2 + 10s + 150))....
please help me out here if anyone knows how to write in the m.file(MATLAB)....thanks |
