I am thinking that circuit #1 is a low-pass filter because of the cap and resistor in series on the feedback leg
#2 I am thinking that is a high-pass filter
I am thinking this one is also a low-pass filter based on this article
haha one of those looks awfully familiarLM102 Datasheet, Page 5 shows examples of high pass and low pass filters.
You might recognize a circuit on that page as well.
Presumably you refer to that somewhat blurry colored figure?the second one is neither a band-pass filter or a high-pass filter.
I have failed at op-amp circuit identification. LOL
Prof says that it is an AC noninverting op ampPresumably you refer to that somewhat blurry colored figure?
I would have thought 'effectively' a high pass filter.
There are two poles at ω=1 rad/sec and ω=10 rad/sec. There are two zeros at ω= 0 rad/sec (i.e. DC) and ω=0.1 rad/sec.
So DC gain is zero. Gain rises from 0 to 0.1 rad/sec at 20dB per decade. From 0.1 rad/sec to 1 rad/sec the gain rises at 40dB per decade. From 1 rad/sec to 10 rad/sec the gain rises at 20 dB per decade and from 10 rad/sec the gain begins to level out to a final high pass value of 20dB.
What is the correct answer according to your teacher?
I agree.As Jony130 correctly indicated.
Interestingly, if one were presented only with the Bode plot (magnitude / phase frequency response) rather than the circuit diagram itself, then it would be equally valid to state the response as being consistent with that of an active high-pass filter.
