RADIO

無(wú)線(xiàn)電廣播是以無(wú)線(xiàn)電波為傳輸廣播節(jié)目載體的廣播方式。世界公認(rèn)的首次電臺(tái)播音是1920年11月2日美國(guó)威斯汀豪斯公司在匹茨堡的KDKA電臺(tái)播出哈定當(dāng)選總統(tǒng)。此后,蘇聯(lián)、英國(guó)以及中國(guó)等許多國(guó)家紛紛建立了廣播電臺(tái)。

  • 射頻集成電路設(shè)計(jì)John Rogers(RADIO Freq

    RADIO Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog integrated circuit designers in the past workedon applications at low enough frequency that microwave issues did not arise.As a consequence, they were adept at lumped parameter circuits and often notcomfortable with circuits where waves travel in space. However, in order todesign RADIO frequency (RF) communications integrated circuits (IC) in thegigahertz range, one must deal with transmission lines at chip interfaces andwhere interconnections on chip are far apart. Also, impedance matching isaddressed, which is a topic that arises most often in microwave circuits. In mycareer, there has been a gap in comprehension between analog low-frequencydesigners and microwave designers. Often, similar issues were dealt with in twodifferent languages. Although this book is more firmly based in lumped-elementanalog circuit design, it is nice to see that microwave knowledge is brought inwhere necessary.Too many analog circuit books in the past have concentrated first on thecircuit side rather than on basic theory behind their application in communications.The circuits usually used have evolved through experience, without asatisfying intellectual theme in describing them. Why a given circuit works bestcan be subtle, and often these circuits are chosen only through experience. Forthis reason, I am happy that the book begins first with topics that require anintellectual approach—noise, linearity and filtering, and technology issues. Iam particularly happy with how linearity is introduced (power series). In therest of the book it is then shown, with specific circuits and numerical examples,how linearity and noise issues arise.

  • 無(wú)線(xiàn)電干擾 RADIO Susceptibility

      Abstract: Engineers often wish that RADIO susceptibility (RS) or RADIO immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from RADIO frequency interference.

    GPRS(General Packet RADIO Service)是通用分組無(wú)線(xiàn)業(yè)務(wù)的簡(jiǎn)稱(chēng)。GPRS是GSM Phase2.1規(guī)范實(shí)現(xiàn)的內(nèi)容之一,能提供比現(xiàn)有GSM網(wǎng)9.6kbit/s更高的數(shù)據(jù)率。GPRS采用與GSM 相同的頻段、頻帶寬度、突發(fā)結(jié)構(gòu)、無(wú)線(xiàn)調(diào)制標(biāo)準(zhǔn)、跳頻規(guī)則以及相同的TDMA幀結(jié)構(gòu)。因此,在GSM系統(tǒng)的基礎(chǔ)上構(gòu)建GPRS系統(tǒng)時(shí),GSM系統(tǒng)中的絕大部分部件都不需要作硬件改動(dòng),只需作軟件升級(jí)。
