ya skeptic2...i don't expect you to breadboard the circuit but i just asked in-case you or somebody else has already done that. i know how to adjust the R and C values after all how did i design higher order circuits. but MicroSim evaluations have proved to be a disaster...i made the same...

thanks for the ckt but it does not involve coupling of two Butterworth filters, which i need to do. btw i saw that texas link days before...it was not of much help because they have not given specific values for R and C. one more thing (as i mentioned earlier), the MicroSim/PSpice simulations...

Band reject: 1kHz to 2kHz It has to be Butterworth type. AS such no restrictions on dB of rejection but has to be made by coupling Firt Order BW HP and First Order BW LP filters. By the way i tried out constructing Higher order BW HP and BW LP filters. I made band pass and band reject out of...

any references or circuits?

k...thanks, will surely try that. but i am still expecting more replies and suggestions.

I have uploaded the circuit diagram, please have a look at 3rd pic. Ain't it correct to couple the op-amps in parallel arrangement for band reject?

Hi friends, I have just started to work on active filters and designed the following: 1. 1st Order HighPass BW (cut off @ 1kHz) 2. 1st Order LowPass BW (cut off @ 2Khz) 3. Band pass using above two (1kHz to 2kHz) 4. 2nd Order HighPass BW (cut off @ 1kHz) 5. 3rd Order HighPass BW (cut...
