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 average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

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 ...

Overcoming the issues of DC offset in Direct Conversion for Software Defined Radios. Modulation is a process by which characteristics of a high-frequency carrier signal are altered to convey ...

March 13, 2013. Tektronix Inc. today announced a new software option for its OM4000 optical modulation analyzer series that offers automated test support for 400G multicarrier coherent optical ...

It was once a strongly held opinion that there were only four types of effects processors. There were those that affect frequency, those that affect time, those that affect amplitude, and those that ...

Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

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, ...
