Choosing the Right Mixed-Signal Test Equipment News & Analysis 10/30/2002 Post a comment Today's high-speed, mixed-signal measurements challenge the capabilities of traditional test equipment. Agilent's Dave Sontag describes three different mixed-signal analysis solutions that provide time-correlated views of both analog and digital data, along with the strengths and weaknesses of each one.
Using FPGAs for Software Radio Systems Design How-To 10/8/2002 Post a comment During the last decade, designers have used ASICs and DSPs to handle nearly all of the signal-processing functions associated with radio communications. Pentek's Rodger Hosking discusses the latest generation of FPGAs, which are so powerful that they're now displacing both ASICs and DSPs in the latest software-radio applications.
Evaluating Performance Tradeoffs in a Dual-Mode, W-CDMA/EDGE Digital IF Receiver Design How-To 10/7/2002 Post a comment The need for and use of multi-band phones is rapidly increasing. Agilent EEsof EDA's Kal Kalbasi examines performance tradeoffs in a dual-mode phone that supports both the Wideband Code Division Multiple
Access (W-CDMA 3GPP) and Enhanced Data rates for GSM Evolution (EDGE) standards. Kal also discusses the use of Error Vector Magnitude (EVM) measurements as an alternative to BER for faster simulations of receiver front-end performance.
Blog Doing Math in FPGAs Tom Burke 1 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
