Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

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 ...

DENVER — A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to ...

This chapter covers the following subjects: Wireless Local-Area Networks: A brief history of wireless networking and some of the basic concepts. How Bandwidth Is Achieved from RF Signals: The ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Three innovative design techniques substantially enhance wireless transmitter performance and can boost power efficiency and elevate data rates concurrently. This effectively aligns with the growing ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many occasions, such as electronic warfares, wireless communications and modern radar systems. Initially, ASK ...

Complex, highly sophisticated communication is fundamental to the human experience — to being human. Play is likewise important to our intellectual, creative, and social development. Today much of our ...

Power-density improvements are an increasingly elusive goal as designers exhaust the easiest or most obvious solutions. One direction that’s now being explored more thoroughly is advanced modulation ...

The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...
