Filter circuit for audio
Hi all,
I am designing one circuit (as a hobby) to amplify the audio of fan. I expect the sound signal will be around 0-8kHz. But when I feed this signal as such to loudspeaker, I am hearing some trebles, noises etc...
So we need a filter... my questions are like this?
1. is simply providing can help in filtering out noise?
2, if filter is the ideal, which filter would be good to use?
