i m new to this subject... i m little confused over voice sampling... it is easy
for me if voice were composed of single frequency... but voice is made up of a
band of frequencies... how one sample at a paticular instant sould look
like....because one sample would mean simultaneous amplitudes of many
frequencies... so how a code is assigned to a sample that is made up of many
amplitudes...
thanks in advance...

Consider time domain representation of 2 sine waves of frequencies f1 and
f2 respectively. When you add them, what happens? [try to draw them.] While
taking samples you take into consideration the Time Domain representation of
the combined signal. So, while assigning the code - it's not assigned to two
waves differently - but to their combination.
