Hello all,
I've got a question with regards to sketching Bode plots.
I'm supposed to sketch the bode plot of my transfer function,
\(T(s) = \frac{-390000 - 0.585s}{164368 + 0.019302s}\)
by hand.
EDIT: Whoops! I think I mixed my zeroes and poles up!
I should have a zero at,
\(\omega_{z} = \frac{390000}{0.585}\)
and one pole at,
\(\omega_{p} = \frac{164368}{0.019302}\)
When we compute these, it seems as though the zero occurs at a high frequency than the pole, so the bode plot would resemble a low pass filter, but when I modeled the circuit in Multisim it gives me a graph like the following,
I attached the original schematic of the circuit I'm working with as well incase someone can tell by inspection whether the circuit will act as a low, or high pass filter.
There is a possibility I may have made an error in my calculator computing the values of the transfer function, but I'd like to be sure before I redo all my calculations. (There's alot, and it's really messy)
EDIT: I just redid my calculations again and I arrive at the same result. Am I misunderstanding how to plot the bode plot correctly?
Now that I've got my zeros and poles sorted out, my plot should match this one!
What do you guys think?
