Can someone point me to the error in the circuit design (bandpass filter)?

Post by yaantey »

I have attached a bandpass filter I have constructed and simulated. The frequency range of the band pass filter is 704 Hz to 2040 Hz. But the problem is even when I put 60Hz I am still getting the same input wave at the out. So, what's wrong with the circuit and can someone correct it for me (Please explain in a simple and easy way to understand, cuz I am a newbie).

Thanks.

Is there a flaw in the schematic? The junction between R1 and R2 and C2 and R3 are not connected in your drawing...seems strange :?
