Hi to all,

I am using external 13 bit ADC witch originally won't necessary
to go that high resolution "not under my control" now the result
I am getting is noisy numbers are going high and low. what I did is
reading it 10 times then I add them together then divide it by 10.
It helps but one of our engineer asked me to add software low pass
filter witch I am familiar with it. Reading 10 times values are up to 15 point
different. 
My question is do you have any experience or know how software LPF work?
any link or info will appreciate. I searched piclist.com not enough info
I found to understand what to do.

thank you for your help

Andre
