Comparative Study of PLL, DDS and DDS-based PLL Synthesis Techniques for Communication System

The phase locked loop(PLL) has been widely used in wireless communication systems due to the high frequency resolution and the short locking time. The Direct Digital Synthesis(DDS) is also an emerging and maturing signal generation technology. But another advanced technique in which, DDS signal is mixed with the voltage-control oscillator output in the PLL feedback path. This solution helps in ...

6 HIGH SPEED DACs AND DDS SYSTEMS

A frequency synthesizer generates multiple frequencies from one or more frequency references. These devices have been used for decades, especially in communications systems. Many are based upon switching and mixing frequency outputs from a bank of crystal oscillators. Others have been based upon well understood techniques utilizing phase-locked loops (PLLs). This mature technology is illustrate...

"See me, feel me, touch me, heal me".

Community-based wind energy projects, with their small-scale, yet sizeable presence, provide a valuable opportunity to understand how individuals make sense of changes to their communities and to the surrounding landscape. Here, we examine the results of a 2013 mail survey of individuals residing in the vicinity of a 2 MW wind turbine that is located on the edge of the historic coastal town of ...

Riv Psichiatr 2016; 51(4): 164-165 Domenico Ghirlandaio (1449-1494) fu considerato da Giorgio Vasari, il celebre autore delle Vite, uno dei principali pittori della propria epoca data l’alta qualità e la moltitudine delle opere che concepì e realizzò. Oggi, nonostante il suo stile non corrisponda più alle aspettative del gusto, è impossibile negare quanto il maestro di Michelangelo abbia influi...
