SMH: Direct RF Sampling with High Performance ADC
August 29, 2008 10:11 am | by Philip Pratt, Texas Instruments | Articles | CommentsPreviously analog-to-digital converters (ADC) at high input frequencies were limited in usefulness due to distortion and noise performance. Today, however, ADCs can provide nearly 9.5 bits of effective number of bits (ENOB) at radio frequencies (RF) of 1 GHz with signal bandwidths greater than 200MHz. Such performance at high frequencies eliminates a mixer stage, simplifying receiver design to improve overall system performance.
Embedded Systems: Sniff ZigBee Packets
August 29, 2008 9:14 am | by Jon Titus, Senior Technical Editor | Articles | CommentsWhen engineers tackle a project that uses ZigBee communications they may get a surprise. Unlike point-to-point communications, ZigBee involves a network that can establish nodes, repeaters and complex mesh topologies. The proper test tools--often called "sniffers"--help engineers diagnose ZigBee-network problems that could otherwise turn into nightmares.
