Digital modulation techniques can also be classified according to the type of signal that is being modulated. Amplitude modulation (AM) is the most common type of digital modulation.

Phase modulation Another form of modulation that is widely used, especially for data transmissions, is Phase Modulation (PM). As phase and frequency are inextricably linked (frequency being the rate ...

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.

Measuring Modulation Oct 1, 2004 12:00 PM, By John Battison, P.E., technical editor, RF The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or ...

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

LFOs, or low-frequency oscillators, can ‘modulate’ other parameters on a synth and it’s this ‘modulation’ that really takes sound design up a layer. When you master this type of design, you can create ...

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing.
