Hi
I want to design a circuit to which I would feed in a sinusoidal signal of any frequency but always the same amplitude say 1V. The output should be 1 V for only two input frequencies (f1 and f2) and zero for any other input frequency. Can anyone suggest how I should go about it? How do I create such a sharp filter and that too with two peaks at f1 and f2 ?
Thanks

What I can think of is to design two very sharp bandpass filters centered at f1 and f2 and then cascade them. Whats your take on this?
