Is there a way I can design a broadband reject filter using a lowpass filter with cutoff frequency f_1 and a highpass filter with a cutoff frequency f_2,\ (f_1 \ll f_2) , combined in parallel with a summing amplifier? My current design yields a response that isn't a broadband, there is a significant bump at the center frequency. If I cannot do so, will I have to use a ramp up and a ramp down?
Sorry for having a run on sentence.

try higher order equial ripple band stop filter design pattern.
