Homework Statement
Given the transfer function:
Find the phase relationship between the input and output voltage at high frequencies
Homework Equations
NA
The Attempt at a Solution
My approach was to find the phase of the transfer function, which I got to be:
I assumed that "very high frequencies" meant w = ∞, plugging it in, I get the answer to be 0°.
However, the answer from my teacher was that it was -180, because the transfer function had 2 poles, each at -90. While I can understand this, I wanted to know why my method was wrong.
