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 ...

Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...

A new technical paper titled “Reconfigurable signal modulation in a ferroelectric tunnel field-effect transistor” was published by researchers at Lund University in Sweden. “Reconfigurable transistors ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published by researchers at NaMLab gGmbH, GlobalFoundries, and TU ...

On a high: do muons and neutrinos mimic DAMA's signal? The DAMA/LIBRA experiment is located deep below Gran Sasso mountain in central Italy. (Courtesy: LNGS) For the last 16 years, researchers at the ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

First I’ll tell what you already know. Back in the day, AM broadcasting was king and FM was commercial-free. Things changed in the 1970s as FM grew in popularity. Here we are 40+ years later with many ...

Intel Corp. today debuted a new and significantly faster version of its Thunderbolt technology, which is used to connect personal computers with external devices such as displays. Thunderbolt was ...
