Steven R. Norsworthy

Although practicing full-time engineering since 1983, Steven started out his early career as an orchestral trombonist, conductor, and university music instructor. He received Bachelor’s and Master’s Degrees in Music, studying trombone with Donald Kneeburg and conducting under Robert Summer. He also studied trombone with the late Thomas Beversdorf, while Steven was the principal trombonist in the Indiana University Summer Festival Orchestra. He has participated in choral conducting master classes with Sir David Willcocks. From 1978-80, he was Assistant Professor of Low Brass at the University of New Hampshire (UNH). Two of his UNH students later became university-level trombone instructors and successful professional trombonists.

As a trombonist, Steven held orchestral positions with the Florida Orchestra, the New Hampshire Symphony, the Pennsylvania Symphonia, the Lehigh Valley Chamber Orchestra, and the Allentown Symphony. In 1980, he was admitted into the Doctoral music program at Northwestern University to study trombone with the late Frank Crisafulli, but instead choose to pursue a full-time career in engineering, however, he continued active as a free-lance trombonist and conductor.

After completing his engineering degrees, he started his career with AT&T Bell Labs as a research engineer in the areas of digital signal processing and data conversion, and authored papers, new inventions, patents and a book which has become the most cited reference in its subject area. In 1996, he became the Worldwide General Manager of a business unit of Motorola.

Steven is a world authority in the engineering fields of RF mixed-signal architecture, the ‘father’ of the world’s first single-chip Bluetooth, the co-author of the first textbook on Delta-Sigma Data Converters (which you use every time you listen to a musical recording or talk on the phone), and an inventor on 25 issued US patents with additional new patents pending. He is currently a consultant on Intellectual Property, strategic sales, mergers, and acquisitions, to technology companies.

Recently, he has rekindled his interest in the trombone, and is conducting independent research and experiments for improving the sound and playing response of trombones.
