Introduction to Millimeter Wave Wireless Communications
By Theodore S. Rappaport, Robert C. Daniels, Robert W. Heath, James N. Murdock
Oct 6, 2014
Communication at mmWave operating frequencies represents the most recent game-changing development for wireless systems. The authors of Millimeter Wave Wireless Communications discuss the need for new, interdisciplinary strategies to create the ever-evolving broadband wireless devices and systems at mmWave, and beyond.
What Is Bluetooth Low Energy?
By Robin Heydon
Nov 21, 2012
Robin Heydon explains what BlueTooth low energy is, as well as relevant device types, design goals, and terminology.
Practical Applications in Digital Signal Processing: Review of Digital Frequency
By Richard Newbold

Introduction to High-Speed Signaling
By Kyung Suk (Dan) Oh, Xing Chao (Chuck) Yuan
Nov 9, 2011
This chapter explains the means by which the book High-Speed Signaling: Jitter Modeling, Analysis, and Budgeting offers a comprehensive discussion of high-speed signal integrity engineering.
Notes on Digital Signal Processing: Overview of Sampling Techniques
By C. Britton Rorabaugh
Jan 26, 2011
This note discusses the difference between implicit and explicit sampling. It introduces three different mathematical models of explicit sampling techniques—ideal sampling, natural sampling, and instantaneous sampling.
Understanding Digital Signal Processing: Discrete Sequences and Systems
By Richard G. Lyons
Nov 15, 2010
In this introduction to his book, Richard G. Lyons defines the terminology used in digital signal processing, illustrates the various ways of graphically representing discrete signals, establishes the notation used to describe sequences of data values, presents the symbols used to depict signal processing operations, and briefly introduces the concept of a linear discrete system.
Introduction to Power Integrity for I/O Interfaces
By Vishram S. Pandit, Myoung Joon Choi, Woong Hwan Ryu
Oct 28, 2010
It is becoming increasingly essential to determine not only the PDN noise, but also the margin degradation due to the noise coupling to signals. System designers need to consider a concurrent design methodology to evaluate power integrity and its effects on signal integrity.
Introduction to Notes on Digital Signal Processing: Navigating the DSP Landscape
By C. Britton Rorabaugh
Jan 18, 2010
This introduction to Notes on Digital Signal Processing explains the book's method of documenting in-depth explorations of some of the "nooks and crannies" in DSP that often are glossed over in traditional texts.
Signal and Power Integrity: Time and Frequency Domains
By Eric Bogatin
Jul 22, 2009
In this chapter, learn the basic properties of signals in preparation for looking at how they interact with interconnects.

What are Bluetooth Profiles For?
By Jennifer Bray
May 11, 2001
Bluetooth uses profiles to keep devices interoperating smoothly and easily. In this article, Jennifer Bray explains how Bluetooth profiles are used and offers hints of those to come.
How Many Bluetooth Piconets Fit in a Room?
By Jennifer Bray
May 11, 2001
Ever wondered how many Bluetooth piconets you can fit in a room before they stop working? That's a tough question because of all the variables involved. Jennifer Bray takes a stab at the answer in this article.
How Fast is Bluetooth?
By Jennifer Bray
May 11, 2001
Perhaps you've heard data rates quoted for Bluetooth that range from 1 megabyte per second to a few kilobits per second. Why so many different figures? Jennifer Bray gives you the straight scoop on the factors that affect Bluetooth data rates.
Masters and Slaves: Roles in a Bluetooth Piconet
By Jennifer Bray
May 11, 2001
To understand how the master-slave switch works, you must first understand the roles of master and slave in a Bluetooth piconet. To understand that, you have to know about Bluetooth frequency hopping. Jennifer Bray takes a look at that topic here.
Why Bluetooth 1.1?
By Jennifer Bray
May 11, 2001
If you're wondering what changed between Bluetooth version 1.0b and version 1.1, you've come to the right place. Jennifer Bray points out the differences between the two versions and explains why the changes were necessary.
