Actually i think that the communication speed is very limited which prevents the signal to be acquired completely.

Again, why do you think that?

How would the communication speed affect the acquisition?

See many earlier replies in this thread, including: http://www.8052.com/forum/read/180994

Look again at your plots - it looks very much like you are taking too few samples in the first place.
