Greetings,
I spent a little time reviewing Bode plots. (it's been a while)
I was playing with the phase response of a plot and it did not seem obvious to me that the phase response should be (minus arctan())
Now, when the transfer function has no poles in the denominator, the book states that the phase response is arctan() (no minus sign).
I've attached a sketch of my thoughts.
Can you explain why the minus sign?
By the way, my book simply states the equation with no reason, a second book simply stated, "note the minus sign"
Thanks
