Yes, I can. Can you do your homework on your own?

Since this is obviously homework, I'm only going to point you in the right direction: Look up "quantization". An analog signal is continuous in time and value, but a digital representation has to fit into a specified number system. What happens when an input happens to fall "between the cracks" in time or level?
You might also want to look up "aliasing" and "sampling theory" while you are at it.

can you list three important aspects of using digital representation of analogue signals? "Lord Garth" ¼¶¼g©ó¶l¥ó·s»D:h8q2e.5811$ snipped-for-privacy@newssvr12.news.prodigy.com...

Possibly. Can you be more specific? For example, what does "aspects" mean?
Thanks, Rich

An aspect is a view of something, or a way to see it, a way it can be used.
I can see a cow as a milk-producing animal, or as a valuable property, or as a symbol for something holy (in India), or as an example of a four-legged animal.
One aspect of computers is that they allow us to communicate globally via internet. Another aspect is that computers are cute to look at and make nice sounds.
digital representation of analogue signals
is a way to convert analogue signal so we can process and store the signals in modern digital devices
allows us to store analogue signal in computers, like we do with music, mp3-players.
allows us to use digital signal processing on the signal, like the DSP processor on your sound card, which allow you to change the echo effects (big hall, concert hall, church) on everything you play
it sacrifices some of the precision in the analogue signal through digitalization, but we gain other advantages from the transformation.

sorry , can you explain what is the meaning of aspect to me? because i think there are many aspects of using digital representation of analogue signals
thanks!
the question is "list three important aspects of using digital representation of analogue signals"?
many aspects of using digital representation of analogue signals,but which three are important? becasue many aspects are also important.
so i fell very confuse of that question.
thanks!
