A family of signals is considered which lie within a bandwidth of W cps. Methods are discussed of experimentally obtaining suitable discrete numbers at the rate of 2W per second to describe completely any given member of the family. An "Educated Direct" sampling method is presented and compared with previously known sampling methods.
