When doing PCB designs, we come across different types of filters requirement. Currently am doing a project that involves the 4th and 6th order active band stop filters. Anybody who has an idea on how this filters can be designed ? I really don't have an idea and your help is highly welcomed.

thank you!

Your guidance was very impressive. Currently am done with the schematic design of the filters. I did it using the NI multism as you directed. Check the attached end results in the document below;

I have done the manufacturing of the above-attached circuit for the 4th and 6th order active band stop filter through and received the order back. Am currently in the testing process and I think the circuit is not giving the best functionality as I expected. The manufacturer has done a good job as per my design but I think there were several errors during the design process that has affected its performance.
