This practical, hands-on resource describes functional units and circuits of telecommunication systems. The functions characterizing these systems, including RF amplifiers (both low noise and power amplifiers), signal sources, mixers and phase lock loops, are explored from an operational level viewpoint. And as all functions are migrating to digital implementations, this book describes functional units and circuits of telecommunication systems (with radio, wire, or optical links), from functional level viewpoint to the circuit details and examples. The structure of a radio transceiver is described and a view of all functional units, including migration to SDR (Software Defined Radio) is provided. Chapters include a functional identification of the units described and analysis of possible circuit solutions and analysis of error sources. The sequence reflects the actual design procedure: functional identification, search and analysis of solutions, and critical review to provide an understanding of the various solutions and tradeoffs, with guidelines for design and/or selection of proper functional units.
"What begins as a sunny August afternoon on a bucolic lake turns into a tragedy when a Jet Ski swerves fatally close to shore. It's a day Ellen Banks could never have prepared for, a day no mother should ever have to live through." "The moment her son James is killed, Ellen must face the unimaginable while trying to remain strong for her older son, Daniel, who witnessed the fateful accident and blames himself. Ellen's shock and grief soon give way to defiance as lawyers and policemen who once vowed to support Ellen's desire for justice succumb to political pressure and back away. Still, Ellen is determined to see the reckless young man pay for his crime and to heal her family's deep wounds. But first she must heal herself." "All the Numbers depicts a woman's reckoning with her own vulnerability and finding in the wisdom of motherhood the redemptive grace to begin again."--BOOK JACKET.

Mussolini&’s bold claims upon the monuments and rhetoric of ancient Rome have been the subject of a number of recent books. D. Medina Lasansky shows us a much less familiar side of the cultural politics of Italian Fascism, tracing its wide-ranging efforts to adapt the nation&’s medieval and Renaissance heritage to satisfy the regime&’s programs of national regeneration. Anyone acquainted with the beauties of Tuscany will be surprised to learn that architects, planners, and administrators working within Fascist programs fabricated much of what today&’s tourists admire as authentic. Public squares, town halls, palaces, gardens, and civic rituals (including the famed Palio of Siena) wer...
In a masterly synthesis of historical and literary analysis, Giuseppe Mazzotta shows how medieval knowledge systems--the cycle of the liberal arts, ethics, politics, and theology--interacted with poetry and elevated the Divine Comedy to a central position in shaping all other forms of discursive knowledge. To trace the circle of Dante's intellectual concerns, Mazzotta examines the structure and aims of medieval encyclopedias, especially in the twelfth and thirteenth centuries; the medieval classification of knowledge; the battle of the arts; the role of the imagination; the tension between knowledge and vision; and Dante's theological speculations in his constitution of what Mazzotta calls a...
