Spin Semiconductor

Well, I am learning about FV1 now.

I would do like to receive help about algorithm and software for FV1 platform for aplication in my audio variable filter for water leakage detection.

The goal this project is to find water leakage in barrel into the wall or into the ground with few destruction.

Thanks for your help...

Interesting use of the FV-1 but I have no idea where to start for such a device. It would seem to me that every leak will be different in terms of sound so what is the characteristic you will be checking for?

I'm starting to learn programming fv1.

So you basically need an adjustable bandpass filter so you can sweep through the range of interest. I don't have a program off hand to assist here (I'm mostly a h/w guy, did the digital design in FV-1) but a search in Google or Yahoo should give you some simple bandpass structures to use.

Maybe a simple state variable filter will work, for an example see:
