( For the active filter circuit in (a) sketch the circuit. Then given that Ri = 10 kΩ, Ci = 10 nF, the feedback resistor Rf = 500 kΩ and the op-amp is a 741, determine the values of;(i) The -3-dB frequency.(ii) The time constant τ (in milliseconds) (iii) The maximum voltage gain of this circuit in dB.(iv) The voltage gain in dB at a frequency of f = 1 kHz.

i thought we has set up some sort of pay scale/service fee for instances such as this .

really though ... like mack says ... show us what effort you have put into figuring this stuff out for yourself .

We did. IIRC, it's $10,000USD per hour, with the price dropping by $1000/hour for every hour the poster has spent trying to solve the problem for themselves. Proof of time spent is required. Posting the results of your own attempts is acceptable proof.

BTW: I am, of course, only joking. But we won't just answer your homework questions for you, as you don't learn that way.What we will do is help you learn to do it yourself.
