filter impedance matching

hi guys,
what do this term means:

1) reflected bandwidth
2) Reduce inteference
this interm of filter and impedance matching

thanks

Are you sure about this terms?
Where did you find them?

Bye

Hi,

reflected bandwidth could be out-of-passband (where filter reflects). If it is bandstop filter it should be its main feature. Think if some signal is not stoped (bandstop filtered) from going into critical cicuit than it can couse parasitic mixing or saturation i.e. application of a bandstop filter can reduce the interference...

Only guesing, but nothing else could make sence to me
