Vladimir Kotelnikov is a prominent Russian engineer and scientist, best known for his contributions to the fields of radio engineering and telecommunications. He is particularly noted for his work in the development of the Kotelnikov theorem, which relates to the sampling of signals, and has fundamental implications for digital signal processing and communications. Kotelnikov's theorem dictates the conditions under which a signal can be accurately reconstructed from its samples, providing a theoretical foundation for the conversion between analog and digital signals.
