It's out of my hands RF & Microwave Designline Blog 3/26/2008 Post a comment Recently, in my home state of NJ, police received the authority to stop and fine motorists for using hand-held cell phones while they drive. But are we actually safer?
'How to Cheat': The Physics of RFID Design How-To 3/25/2008 Post a comment Here is the first section of Chapter 2 from 'How to Cheat at Deploying and Securing RFID.' The chapter--The Physics of RFID--provides a basic understanding of the physics of RFID communications and the characteristics that affect system performance during the journey of an RF wave.
Radio Architectures, Pt 5: ADCs and Receivers Design How-To 3/24/2008 Post a comment Wish you knew more about radio architectures? Then this series is for you. This final part takes a closer look at the importance of ADCs in relation to front end design and offers a case study of a communications receiver.
RDS receivers enhanced for portable, in-car navigation devices Product News 3/19/2008 Post a comment Silicon Labs has expanded its broadcast audio portfolio to include two radio data system (RDS) receivers that meet the growing demand to couple RDS traffic message channel and open data applications with static GPS navigation maps to dynamically route drivers around traffic anomalies.
Under the Hood: Sonos brings multi-zone digital audio to life Teardown 3/18/2008 Post a comment The designers of the Sonos Digital Music System made four inspired design decisions early on to realize its ground-breaking, multi-room digital audio system, but deep into the design process, even they were humbled by the intricacies of effective wireless system design. See why.
Hardware needs limit software radio Design How-To 3/7/2008 3 comments This paper presents major design and implementation issues and reaches the conclusion that even using intensive software processing, the attempt to design a real world software radio will result, contrary to common expectations, in a big, heavy, power hungry and very expensive device.
Galileo sat-nav test bird set for April launch News & Analysis 3/7/2008 Post a comment Galileo, Europe's technically advanced but politically mired satellite navigation project, is set to hit the airwaves again as Giove-B, the second demonstrator spacecraft , has been given a late April launch date.
RFID Essentials: An Introduction to RFID--Part III Design How-To 3/6/2008 1 comment RFID--What is it? Here is the third segment of an excerpt from Chapter 1 of RFID Essentials. This multi-part series will take you from nuts and bolts, through challenges, all the way to adoption guidelines. This week features a focus on applications.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
January 2016 Cartoon Caption ContestBob's punishment for missing his deadline was to be tied to his chair tantalizingly close to a disconnected cable, with one hand superglued to his desk and another to his chin, while the pages from his wall calendar were slowly torn away.122 comments
