A 6db change in signal level is one bit position in a binary value --
2 times the voltage (note that this is 4x the power if driven into the
same load resistance, which is why +3db is twice the perceived power).
If you have a 10 bit converter you can resolve 10 double-ings of voltage
or 60 db.
Hi MS,
Thanks for all your help. Now I'm trying to learn to use TOSSIM while a
can't use motes at Lab.

Dear MS
Thanks for you grat help.
I just can't understood about the range at the end of your message.
Clould you give-me more details?
Thanks for all
PS: Sorry for my bad english

SPL is measured as an average
Hi dear all
I am working on an acoustic project within tinyos-2.x environment.
The goal of the project is to take a view of the distribution of SPL
(Sound Pressure Level) in an ambience.
I took just a few of steps on that, and a this time I'm looking for
documentation about how to take datas
SPL is measured as an average of the instantaneous values you get from,
for instance, a microphone. What you need to do is sample the mic at some
reasonable rate (making some assumptions about the frequency range you are
interested in). In T1 there is a HighFrequencySampling demo app that sorta
