 Hi,

I am a very new user of Psoc.  My project is a device like a phonocardiograph . As input I am getting an audio signal of heart beating captured with mic. The signal is noisy and I am looking for a filter to clear the signal before frequency filtering and other processing. 

Very appriciate your help!

Thanks

Note you can run the DFB wizard to change the parameters for the filter.

Right click component.
