You are exactly right! Thanks for the reply! The funny thing is i figured out what it was at about the same time you replied. I was super happy then i went to email my professor and saw your comment lol. Thank you JESUS!!
where is the bridge completed basically it is like passive filter of rc combination and in case if u think it is complete bridge then a whole circuit will be in all called as a instrumentation amplifier with bridge and its output will be a square wave
hi, this OpAmp circuit looks like an oscillator, thats why the circuit wasn't specified, probably, i think you can use a general purpose OpAmp like LM393, LM358,,, just you have to know electrical caracteristics you need at the signal Vout (frequency, amplitude, impedance...), don't forget to see datasheet of OpAmp circuit choised. i hope all'wright.
A LM393 CANNOT be used since it is not an opamp but an comparator. And the question was already answered and you are indeed right, it is an oscillator (a wien bridge oscillator to be excact ).
