== Abstract&nbsp;  ==

The year 1948 may be regarded as the ''annus mirabilis ''in the emergence of the discipline of signal processing. For in that year [[Claude Shannon|Claude Shannon]] published the epoch-making "A mathematical theory of communication"; Bernard Oliver, John Pierce, and Claude Shannon published the classic argument for the use of pulse..code modulation; modern digital methods of spectrum estimation were introduced; error-correcting codes were introduced; audio engineering achieved a new prominence; and the IEEE Signal Processing Society, albeit under a different name, was established. In addition, that year saw a demonstration of the first stored-program computer and the announcement of the invention of the transistor, heralding two new technologies that would later greatly stimulate signal processing.&nbsp; This article explores the year and its achievements in depth.
