There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...

In our modern era, digital logic has become the core of all the electronics circuits either in the form of an FPGA, microcontroller, microprocessor, or discreet logic. Digital systems use many ...

Clock speed is equivalent to data movement in applications that receive and process hundreds of megabytes of data each second. Applications involved in moving enormous volumes of data include cellular ...

So far we have been looking at the more basic structure of VHDL and using combinational logic circuits. In this article, however, we will look at how to use and interface clock signals, the beating ...

Smaller than conventional devices, made of three small chips plus electronics and optics, new clock is based on semiconductor laser and frequency combs. Coffee time: The heart of NIST’s ...
