There are several modern digital modulation techniques that provide increased information capacity, higher data security and quicker system availability with great communication qualities.

Quadrature modulation is widely used in digital communications systems up to and including 5G. The basic idea behind modulation is to control one or more parameters of an RF carrier by the modulating ...

Part of the reason for the confusion between chorus, phasing and flanging is the close similarity in sound between the three. Arguably the technical differences between them are subtle, but when ...

This coherent modulation imaging method removes inherent ambiguities of coherent diffraction imaging and uses a reliable, rapidly converging iterative algorithm involving three planes.

Fundamentals Of Modulation With radio wave modulation, a transmitter can use changes in phase, magnitude, or frequency to represent either analog or digital information.

The model name refers to a Fourier Modulation (4M) technique the company said it designed and hopes to patent. It uses duty-cycle modulated RF to produce optimum efficiency over the 250 watt to 55 kW ...

Figure 1 PAM-4 uses four distinct voltages to represent two bits (left), which produces three eye diagrams (right). PAM-4 is gaining traction in 28 Gbps links, shown both at OFC 2014 and at DesignCon ...

Kolkata: The city will soon have a specialised ‘neuro-modulation' unit that will treat brain ailments using external and ...
