Sampling Theory and Isao Someya: A Historical Note


Shannon’s sampling theorem was published in 1949. In the same year, a book authored by Isao Someya was published in Japan in which the same theorem was derived along with many extensions and applications. This article provides a brief introduction to Dr. Someya and his work on the sampling theorem.
