- Obtain the bode magnitude values using the "bode" function.
- Convert the values to log scale using the "log10" function
- Plot the obtained values in log10 base against frequency.
Change of scale in Bode Magnitude Plot

Is it possible to have the Bode Magnitude plot in Log10 scale instead of decibels? If so, what is the procedure?
Thank you very much

Hi
I understand you want to plot the bode magnitude plot in log10 scale.
You can follow the following steps for it:
I'm attaching an example code and documetation links for the functions used below
H=tf([1],[1,1]); % sample transfer function
[mag,phase,wout] = bode(H); % obtain magnitude response
magLog10 = log10(mag); % convert to log10 base
magLog10 = reshape(magLog10, [size(wout),1]);
plot(log10(wout), magLog10)
