Document Summary
For all questions, assume op-amps are ideal unless otherwise stated: consider the circuit below, derive an equation for the transfer function. Your answer should be in the form of a single equation (i. e. , solve any simultaneous equations that you establish; this problem is easy enough to solve without a calculator). 2 pts: if vi = 10sin(1e6*t), determine vo. Please simplify as much as you can without a calculator; you should certainly be able to get the answer into the form of a single complex number. 2: derive the transfer function for the following circuit: This is probably a band-pass filter, since r1c1 passes high frequency, while r2c2 rejects high frequencies. Assuming r1c1 < r2c2, this will be bandpass: circuit b is supposed to be an improvement on circuit a . The buffer separates the individual 1st order elements so they don"t load each other: usually, for audio applications, we often find that lc filters are difficult / expensive to use.
