Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Harris Broadcast Communications engineers worked with Tom Ray, corporate DOE at Buckley Broadcasting/WOR(AM) in New York, to test the compatibility of several MDCL algorithms with AM HD Radio and ...
