In a audio conferencing system each persons speech is sampled 4000 times per second and 256 quantisation levels are used for each sample When one person speaks for 3 seconds how much data is sent? Its for a college assignment, but just can not get my head around it. Thank you.

256 quantisation levels = how many bits per sample?

4000 samples for one second, how many for 3 seconds?

Put it all together and what do you get?
(yes, I know the answer, but I don't think I would help if I just gave it to you)
