High-Performance Portable Optical Clock
BackgroundThe device described here is best termed an optical frequency standard. This is a device that outputs a laser which has its frequency stabilised to a reference. This reference can either be an atomic/molecular resonance or a mechanical resonance in a macroscopic object. An atomic/molecular reference typically gives the optical frequency standard...

Method for processing RF signals for receiving and transmission
Summary Radio frequency (RF) radiation is often used in the communication fields for signal receiving and transmission. There is however a lot of interference which needs to be suppressed and the current techniques used for this are expensive and often hard to integrate in to Integrated Circuits (IC's). Integrated circuits are used in almost all...
