Sampling theorem:

If a signal is bandlimited from -B to B.

In order to completely construct the signal, the sampling frequency should be larger than 2B.

Motivation:

The impulse of delta trains with Ts  in time domain (sampling) results in delta trains with Fs.

Ts is inversely proportional to Fs.

Thus, to avoid aliasing effect, Fs should be distant more than 2 B.

That is, Ts should be shorter and more frequent sampling is needed.
