I am using the filter design app to create a Guassian Window bandpass filter. I have successfully used the design tool to create butterworth band pass filters but the Gaussian window appears to not creat the filter correctly. Specifically, the magnitude response does not apply the entered cutoff frequencies .

As it is a FIR Filter, the order of the filter needs to be large enough to give desired results. Try increasing the order of the filter.
