While fewer and fewer people are listening to FM radio today, it was hot stuff amid its widespread rollout during the late 1930s and early 40s. Short for frequency modulation, FM’s appeal compared to ...
John Chowning '66 D.M.A. reflects on his career, his musical journey and the inventions that led to his 2026 win at the ...
The Spectrum Management Authority (SMA) has warned about the risks associated with signal interference and the shared responsibility of entities which use the spectrum to ensure safe airspace ...
Kenya has been using analogue radio, which uses either amplitude modulation (AM) or FM. FM is adopted widely because it gives ...
The 1983 US Postal Service first-day cover for the 20-cent Edwin Howard Armstrong commemorative stamp from the American Inventors series, featuring a Colorado Silk cachet illustrating Armstrong at his ...
Researchers reveal novel mechanisms for decoding bacterial frequency modulation in signal processing
Bacteria employ complex signaling networks for adaptive gene control in changing environments. Bacterial second messenger molecules such as cyclic AMP (cAMP) relay external environmental signals into ...
Abstract: Ground and spaceborne radars can cause severe linear-frequency modulation (LFM) interference in spaceborne synthetic aperture radar (SAR) imagery. To address this problem, it is important to ...
Abstract: Planetary gearbox vibration signals feature amplitude modulation (AM) and frequency modulation (FM) and exhibit cyclostationarity. It is essential to identify the signal carrier and ...
