For the latest installment in Total Guitar’s tone tips we turn our attention to the modulation and filter pedals, which means your flanger, phaser and chorus pedals – and the wah pedal you bought one ...

Researchers use graphene metamaterial to create terahertz modulators with record depth and speed, opening new possibilities for communications, imaging, and sensing. (Nanowerk News) Researchers at the ...

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.200093 discusses dual epsilon-near-zero effect assisted broadband electro-optic modulation. With the continuous and rapid ...

The terahertz range sits between microwaves and infrared light on the electromagnetic spectrum. Despite the potential of terahertz waves in many fields, for example in walk-through security scanners ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

How to use unfiltered PWM to drive high power loads. How to properly set the PWM duty cycle for high power loads. How to drive an incandescent lamp using PWM. Sometimes it’s necessary to drive a ...

In previous posts, I have introduced several do-it-yourself pwm controller circuits and reviewed several Chinese PWM controller modules. The next step in this post is to share the design of another ...
