# Poles and zeros map, High pass filter

Given the following poles and zeros map I have to identify qualitatively, which filter type is represented (Low-Pass, High-Pass, ...). In the solution it says, that this is a high pass filter.

However, I plotted the amplitude response (see below) and to me this looks more like a notch filter or a band stop.

Where is my mistake in reasoning?

Thank You!

Because of the location of zeros, the frequency response magnitude is larger towards frequencies $$\pm \pi$$ and smaller at low frequencies and for this reason it is classified as a highpass filter. However it's not a very successful highpass filter either.
