Following is a graph that provides the comparison between the performances of roofing filters.

Because the center frequency of the filters differ, graphs are overlapped at the center frequency. The frequency indicated as 0 kHz at the center of the Frequency [kHz] axis is the receive frequency.
It is apparent that when down conversion is active, large attenuation is achieved at frequencies other than the target signal.
