"By using pulse position modulation for the code -- the same code used in optical communications for satellites, for example -- we can use very, very little power to communicate and still successfully ...

The history of the 555 timer. What are the 555's modes of operation? About my book to help teach those young and old about 555 timers. element14’s 555 timer contest. The 555 timer celebrated the 51st ...

In order to achieve underwater wireless dynamic optical communication, a laser communication system is proposed based on Pulse Position Modulation (PPM). In order to achieve underwater laser ...

Abstract: Randomizing the positions of charge pump current pulses in a PLL breaks their periodicity and redistributes the reference spurs into broadband noise. Closed form expressions for the power ...

Pulse-width modulation (PWM) is a technique for changing the amplitude of digital signals to control devices and applications that require power or electricity. It effectively regulates the amount of ...

In this review, we report on recent progress in the generation and application of multichromatic polarization-tailored pulse sequences for the coherent control of multiphoton ionization (MPI) dynamics ...

Modulation instability (MI) is a ubiquitous phenomenon in physics, corresponding to the growth of a weakly modulated continuous wave in a nonlinear medium and leading to the generation of a ...

This tutorial is a part of series of MSP430G2 LaunchPad tutorials in which we are learning to use the MSP430G2 LaunchPad from Texas Instruments. So far we have learnt the basics of the board and have ...

Abstract: This paper proposes an initial study on Visible Light Communication (VLC) system consisting of a 20 W flyback converter operating in Continuous Conduction Mode (CCM) with dimmable capability ...
