If one sets a DSP bandwidth greater than the wisest installed roofing
filter the bandwidth will be determined strictly by the characteristics
of the roofing filter and the lowpass filter (4.2 KHz) in the audio
chain.

I understand that the DSP is after the roofing filters but I don't understand
why one can dial in a bandwidth wider then the installed roofing filter. When I
do so, am I hearing the skirts of the filter and the attenuated signals outside
of the filter's passband as well? Thank you.
