当信号采样点数很少时，不能很好的恢复原模拟信号，导致原始信号中的一部分丢失。而当信号的采样点数增多到1024时，其分辨率很好，可以有效的区分信号的信息，当采样点数继续增多时，其恢复为原始模拟信号的精度越高且不丢失原始信号。(When the signal is small when the sampling points can not be good to restore the original analog signal, causing part of the original signal is lost. When the signal is increased to 1024 sampling points, its resolution is very good, can effectively distinguish the signal information, continue to increase when the sampling points, its back to the higher accuracy of the original analog signal without loss of the original signal.)
