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 ...

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Quadrature phase shift key is a one of the digital modulation schemes that use Phase-shift keying. One popular varient of QPSK is offset QPSK or OQPSK. What is the difference between these two ...

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 ...

Modulation effects are early staples of music production and electric instrument soundcraft. As producers, we all know how flange, chorus or phaser effects sound, and we know that the range of sonic ...

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 ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...
