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.

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.

The terahertz quantum cascade laser on its mounting. Credit: University of Leeds Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but ...

Take a crash course in RF modulation types to use on your next project. Did you know the DB-9 connector is actually a DE-9? Building your own underwater ROV tether isn’t as simple as it sounds.

These new devices achieve an unprecedented intensity modulation depth (>99.99%) in combination with a speed of already 30 MHz.

The widening of the selectivity windows of a three-way catalyst under A/F ratio modulation was shown to result from retention of adsorbed species on catalyst surfaces and their subsequent reaction ...
