In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

Many applications require a circuit to perform pulse modulation and voltage amplification to drive a load with a train of impulses. A typical application is driving a piezoelectric generator in a ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

This file type includes high resolution graphics and schematics. Delta-sigma analog-to-digital converters (ADCs) are fascinating—almost mythical in their ability to support low- to medium-speed and ...

An interferometer modulator uses a beamsplitter to produce deflected and transmitted light beams onto mirrored surfaces of a piezoelectric crystal pair, one piezoelectric crystal being driven by a ...

HELIOS Team Will Present Results of 40Gbit/s Optical Modulator Demonstration. GRENOBLE, France, Sep 12, 2011 (BUSINESS WIRE) -- -- At Group IV Photonics Conference, Sept. 14-16, in London: CEA-Leti ...

Abstract: This paper presents the design of a HK-MASH 111 digital delta sigma modulator and a programmable prescaler divider circuit for a fractional-N PLL frequency synthesizer. The maximum operating ...

A friend bought an electric jacket to wear on his motorcycle. But it was on all the time when it was plugged in, which made him sweaty at certain temperature ranges. He was looking for a way to ...

Robotics manufacturers developing the next generation of devices need precise torque control, compact system design, and parts that generate low heat. To meet these needs, Asahi Kasei Microdevices ...
