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...

DDS, 4,4'-diaminodiphenylsulfone, extends organismic lifespan.

DDS, 4,4'-diaminodiphenylsulfone, is the most common drug prescribed to treat Hansen disease patients. In addition to its antibacterial activity, DDS has been reported to be involved in other cellular processes that occur in eukaryotic cells. Because DDS treatment significantly enhances the antioxidant activity in humans, we examined its effect on lifespan extension. Here we show that DDS exten...
