Remote display technology lets users fully experience cloud content
Raj Pawate, Distinguished member, Technical Staff, Texas Instruments Incorporated, May 9, 2012The cloud can provide content almost anywhere, anytime. Often, however, the device where the content ends up is not ideal for viewing, sharing and experiencing it. Remote display technology provides an effective path around this dilemma. More -
High-performance HF transceiver design: A ham's perspective
Doug Grant, May 3, 2012Designers of equipment for radio amateurs face the same problems as designers of most other systems - squeezing the last dB of performance from off-the-shelf components. Some ingenious designs have evolved, using analog, digital and DSP technology. More -
Understanding the basics of setup and hold time
Deepak Behera, Karthik Rao C.G. and Deepak Mahajan, Freescale Semiconductor, April 19, 2012Setup and hold times are treated as intrinsic properties of an element. However, it is the very existence of setup and hold time that often confuses us. Here are the cause of setup and hold time within a sequential element (flip-flop) and a look at the operation of the flop. More -
