Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Schematic diagram of the proposed photonic generation of ASK microwave signals based on SSB modulation. Credit: Frontiers of Optoelectronics (2023). DOI: 10.1007/s12200-023-00075-2 As an ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

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 ...
