Hi
I need a simple RC filter to block audio at 2500hz.
Range would be 2300 - 2700 all other frequencies need to pass.
This is for use in a application where a 8ohm speaker is used for voice announcements and a 2500hz tone burst.
Its the tone I need to reduce.
Can anyone suggest RC values please?
Cheers
Mike
