Note: (1) Close book. (2) One formula 1. The following signals are sampled. In order for their samples to contain all information of a signal determine the range of sampling period T, according to the sampling theorem. (1) (5%) m(t) = 1 + 12x100+ 2 cos(210 x 2000); (2) (5%) m(t) is a rectangular pulse with a width of 10 seconds.
