What is Omega in transfer function?

A transfer function, usually denoted as $ H(\omega) $ or $ H(f) $, is defined to be the ratio of the output voltage to the input voltage as a function of frequency, i.e. $ H(f) = V_out \over V_in $. (Remember that $ \omega = 2 \pi f $.)

What information is contained in a Bode plot?

In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude (usually in decibels) of the frequency response, and a Bode phase plot, expressing the phase shift.

How do you plot the magnitude of a Bode plot?

Bode analysis consists of plotting two graphs: the magnitude of Φ₀(s) with s = jω, and the phase angle of Φ₀(s) with s = jω, both plotted as a function of the frequency ω. Log scales are usually used for the frequency axis and for the magnitude of Φ₀(jω).
