Unless you design EDGE or 3G/UMTS cell phone handsets, you may not have heard of polar modulation. As you know, there are only a few basic types of modulation, but they have been ...

Also known as IQ modulation, the signaling has become a staple in wireless digital communications. It's based on modulating signals that are 90 degrees apart in phase.

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the ...

There are three types of pulse modulation that can be used to build other waveforms with. There are pulse width modulation (PWM), pulse phase modulation (PPM) and pulse location modulation (PLM).

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves ...

5.3.4 Complex modulation A good approach when working with modulation is to utilize the concept of complex modulation , a general method being able to achieve all the modulation types mentioned above.

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the ...

Researchers use graphene metamaterial to create terahertz modulators with record depth and speed, opening new possibilities ...

In the natural world, animals rely on perceiving a range of signals to survive—and for insects, olfactory cues are ...
