When you are trying to digitize a modulated RF signal, you have several choices: you can heterodyne the signal down to a lower intermediate frequency (IF) one or even twice, then digitize; you can ...

The integral role of software-defined radios in today's RF design. Why is an analog-to-digital converter such a key factor in SDRs? How to minimize SFDR to maximize ADC performance with a novel ...

The National Semiconductor ADC12Dxx00 ADCs are dual-channel devices with two completely independent signal chains. Sampling rates from 1.0 to 3.6 Gsamples/s are available. An interleave mode provides ...

A software-defined radio (SDR) uses a general-purpose computer processor to perform aspects of digital signal processing in place of analog circuit hardware. This allows for greater flexibility in ...

Modern SDRs evolve from configurable platforms into intelligent wideband sensing systems combining high dynamic range, ...
