#### The Nyquist-Shannon sampling theorem

**Fundamental bridge between CT and DT**

A continuous signal can be perfectly reconstructed from its discrete version using linear interpolation, if sampling occurred with frequency

가장 큰 주파수 2배 이상으로 샘플링하면 복원가능 because of Frequency-domain representation of sampling for band limited theory. Aliasing distortion을 없에기 위한 최소
