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 ...
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 “Reconfigurable signal modulation in a ferroelectric tunnel field-effect transistor” was published by researchers at Lund University in Sweden. “Reconfigurable transistors ...
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 ...
Angular momentum is the rotational version of linear momentum; conservation of angular momentum is the rotational version of Newton’s law of conservation of linear momentum. Conservation of angular ...
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 ...
Proceedings of the National Academy of Sciences of the United States of America, Vol. 98, No. 5 (Feb. 27, 2001), pp. 2752-2757 (6 pages) The opportunistic pathogenic bacterium Pseudomonas aeruginosa ...
