Edwin Howard Armstrong

Edwin Howard Armstrong was a pioneering American electrical engineer and inventor known for developing key advancements in radio technology. His most notable achievement was inventing the regenerative and superheterodyne receivers, which greatly improved radio reception, making it clearer and more reliable. He also invented FM (frequency modulation) radio, which provides higher sound quality and resistance to interference. Armstrong’s innovations laid the foundation for modern radio communication, broadcasting, and wireless technology, significantly shaping how we transmit and receive audio signals today. Despite facing legal battles over patents, his contributions remain fundamental to modern communication systems.
