Could someone please help me with this problem:
(a) Use physical arguments to determine the value of the transfer function at very small values of the complex frequency, and at very large values of the complex frequency.
(b) Let the input to the above circuit be unit for negative times and zero for positive times. If possible, determine the value of the circuit output at negative times, just after the input switched to zero, and at very large times.
I know that when the frequency is low, then the capacitor becomes an open circuit. When the frequency is high, the capacitor becomes a short.
I redrew the circuit for a low frequency with opens at both capacitors. I see the the input voltage becomes disconnect from the positive terminal of the op-amp, but is still connected to the negative terminal. Does this mean that the output voltage at low frequency is a 0?
At a high frequency, I redrew the circuit again, and noticed that there are shorts connected to both the 5R and 3R resistors. Does this mean I remove those resistors from the circuit as well?
For part (b), could someone please point me in the right direction to get started?
