Critical Techniques for High-Speed A/D Converters in Real-Time Systems
An A/D (Analog-to-Digital) converter, frequently abbreviated as ADC, accepts an analog voltage at the input and produces a digital representation of that voltage at the output that's called a "sample". The two primary characteristics of A/Ds are the rate of conversion or sampling rate, expressed in samples per second, and the accuracy of each digital sample expressed as the number of binary bits or decimal digits per sample.
High-Speed Switched Serial Fabrics Improve System Design (Seventh Edition)
As evolutionary enhancements to the venerable VMEbus, both VXS and VPX deliver significant improvements in data bandwidth, connectivity, power distribution, and cooling. When VME was first introduced, its shared bus backplane interboard transfer rates of 30 or 40 MBytes/sec were more than adequate for most applications. As requirements grew, VME acquired new interfaces such as VSB, RACEway, RACE++, VME64, VME320, and 2eSST, thereby ensuring a healthy community of suppliers and a new stream of products.
Putting FPGAs to Work in Software Radio Systems (Ninth Edition)
Preface FPGAs have become an increasingly important resource for software radio systems. Programmable logic technology now offers significant advantages for implementing software radio functions such as DDCs (Digital Downconverters). Over the past few years, the functions associated with DDCs have seen a shift from being delivered in ASICs (Application-Specific ICs) to operating as IP (Intellectual Property) in FPGAs.
Software Defined Radio Handbook (11th Edition)
SDR (Software-Defined Radio) has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing. This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace legacy analog receiver and transmitter designs while offering significant benefits in performance, density and cost.
