What is the filter and the transfer function that shown below?
i don't think someone will post you the answer, but to put you in the good track, you just use the Fourrier Transform for the impedance because clearly we ar interested in RSP and not transient than just use what you know about op amp, V- = V + = 0 , find the current in Cin - Rin than you can find the Vout and than find the transfer function

Plus, quickly i can say that for DC, it just an inverter amp-op and for the rest of frequency, it is a bandpass filter , but I am not quite sure because Cin and Rin are in parallel.
