Handbook Of Digital Techniques For HighSpeed Design Design Examples Signaling And Memory Techno



Abstract:This paper describes the design, implementation, and testing of a novel multi-function software defined Radio Frequency (RF) system designed for small airborne drone applications. The system was created using an inexpensive Field Programmable Gate Array (FPGA) to combine a coherent linear frequency modulated radar transmitter and receiver, with a Digital Radio Frequency Memory (DRFM) jammer for use with a common RF aperture in simultaneous operation. The system was implemented on a Xilinx Kintex-7 FPGA with a wideband analogue-to-digital/ digital-to-analogue (ADC/DAC) converter mezzanine board and tested using hardware-in-the-loop mode to validate its performance. This is the first known account of an integrated multifunction electronic attack and radar system on a single chip, capable of performing a simultaneous, not time shared, operation.Keywords: radar; electronic warfare; FPGA; electronic attack; digital radio frequency memory; electronic support


In consumer electronics, component digital video signal generation and acquisition may require up to five distinct signals: the three primary video signals, H-Sync, and V-Sync. With T&S, arbitrary waveform generators and digitizers can be synchronized to generate and acquire high-definition video signals respectively, with pixel rates that can approach 165 MHz. CMOS imaging sensors, a technology expected to become mainstream with the prevalence of camera phones and digital cameras, is an example of mixed-signal technology whereby an arbitrary waveform generator, digitizer, and digital pattern analyzer are synchronized for design validation and verification of the chip or chip set.


The array processor digital hearing aid was designed as a research tool (ie, a master hearing aid) for exploring the potential of DSP in hearing aids. An important feature of its design was that it could be used to simulate experimental hearing aids. As illustrated by the preceding account of the difficulties encountered in actually constructing a digital hearing aid, a basic problem in hearing aid research up until that time was that any new idea for improving signal processing required that an instrument be constructed to evaluate the technique. In most cases, the evaluation of the experimental technique was negative, and it was not clear whether the fault lay in the limitations of the hardware implementation or whether it resulted from a fundamental limitation of the technique itself. There are many examples in hearing aid research in which new ideas were tried and found to be wanting and then tried again some time later, with better equipment and usually (but not always) with better results.49


The first commercial sampled-data hearing aid, the Argosy Electronics 3-Channel-Clock hearing aid, was designed by David Preves at the end of the 1980s.106 It consisted of 3 channels with an adjustable frequency response that was far superior to earlier digitally controlled analog devices. The frequency response was determined by the clock rate, hence, its unusual name. The Ensoniq Sound Selector was another early sampled-data hearing aid with low power consumption and excellent frequency-shaping capabilities.107 The instrument was manufactured by an electronic keyboard company and incorporated well-tried sampled data technology that had proven its worth in another highly competitive market. The Ensoniq Sound Selector had 13 frequency channels, allowing for much greater programmable frequency resolution than previously available.


This was a period of rapid change in the hearing aid industry. New hearing aids embodying novel designs with increasingly more complex signal processing were introduced in quick succession by different manufacturers. At the same time, work progressed intensely on developing the ultimate prize: a true digital hearing aid. The main problem in developing a commercially viable digital hearing aid was that of reducing the size and power consumption of the digital chips. Analog chips for hearing aid applications had been refined over many years so that even when digital chips were developed with an acceptable level of power consumption and small enough for use in a practical hearing aid, there remained the problem of competing with analog technology that was well established with chips of even smaller size and lower power consumption. Advances in digital chip technology continued steadily over the years, so that it was essentially a matter of time before digital chips became competitive with analog chips for hearing aid applications.

Blockchains are decentralized digital trust engines that are the underlying technology behind Web3, a loosely defined denotation of the Internet architecture in the years to come, including decentralization of the platform economy of the modern Internet (Web2). In this course, we conduct a full-stack study of blockchains, viewing them as a whole integrated computer system involving networking, incentives, consensus, data structures, cryptography and memory management. The course uses the Bitcoin architecture as a basis to construct the foundational design and algorithmic principles of blockchains. Prerequisites: The basic prerequisites are a maturity with algorithms (COS 226), probability and computer systems (COS 316). Experience with computer security (COS/ECE 432) and networking (COS/ECE 461) will be helpful.
