hope you are all doing well. Right now I am dealing with a homework and I have transfer function and I need to plot the asymptotic Bode Plots of it. I am trying to plot the Magnitude Diagram right now, and I am misevaluating the Magnitude at Low Frequencies. I calculate it as approximately 15dB, whereas MATLAB shows it 35 dB. Here is what I did:
The original question:
What am I missing? I am pretty ill right now, so I am probably missing out a detail, even though I checked it multiple times.
s=0
in the third equation. Due to the pole at origin, the asymptote is a sloping line with —20 dB/decade slope until it reaches the first corner frequency. You can verify by substituting 0.00001 rad/s, 0.0001 rad/s etc fors
in the third equation. Matlab result may be wrong. What doesdcgain(openlooptransferfunction)
give a as output in matlab? \$\endgroup\$
