Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding ...

A crystal radio is a common enough science fair project, but the problem is, there isn’t much on anymore. The answer is, of course, obvious: build your own AM transmitter, too. AM modulation … ...

Amplitude modulation (AM) is widely used for not only wireless communications but also sensing and monitoring biomaterials as well as scientific data. Recently analog multipliers are attracting much ...

Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare reception ...
