SUMMARY
This discussion focuses on designing a broadband bandreject filter using a combination of a lowpass filter with cutoff frequency f_1 and a highpass filter with cutoff frequency f_2, where f_1 is significantly lower than f_2. The user reports issues with their current design, which produces an undesirable response with a significant bump at the center frequency. The suggestion to explore higher order equal ripple band stop filter design patterns is presented as a potential solution to achieve the desired broadband response.
