These Signal Generators Can Test And Emulate Systems Ranging From 2G And 3G To 4G, 802.11b, And Bluetooth. Testing can be one of the most problematic steps in a design chain. When new technologies ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

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 ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

Harvard SEAS researchers have created an electro-optic digital-to-analog converter that bridges electronic and photonic signals for efficient photonic computing and signal processing. The device is ...

In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper ...
