[Openeeg-list] newbi question about digital filters

[devidas b. <dev...@ho...>]

Hi all,

Does properties of a butterworth of Nth order filter same everywhere ?

For example, the bioexplorer has a Butterworth filter which can be set to 2nd order. And Jim Peters has given fiview which also generates code with same name.
Do they have same slope and delay characteristics ?
Or implementing a filter changes it ?

Thanks,

Devidas
