This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

Many of the communication tools of today rely on the function of light or, more specifically, on applying information to a light wave. Up until now, studies on electronic and optical devices with ...

Several countries are building futuristic communication systems using higher frequency electromagnetic waves to transfer more data at faster rates, but they have lacked network components to handle ...

Recently, researchers have developed an integrated electro-optic modulator that can efficiently change the frequency and bandwidth of single photons. The device could be used for more advanced quantum ...

The analysis of RF and microwave signals in the frequency domain used to be the forte of the spectrum analyzer, but now it’s become a choice between signal analyzers and digital oscilloscopes. How did ...

As an ultra-wideband microwave signal, amplitude shift keying (ASK) can be used in many applications, such as electronic warfare, wireless communications and modern radar systems. Initially, ASK ...

Before mobile operators and OEMs can leverage the potential of 5G’s advantages in data speed, ultra-low latency, and greater capacity, they need to overcome several challenges. These range from cost ...

We present mass-correlated rotational alignment spectroscopy, based on the optical excitation of a coherent rotational quantum wave and the observation of temporal wave interferences in a mass ...

Raytheon Co., El Segundo, California, has been awarded a $10,942,488 cost-plus-fixed-fee contract for Technologies for the Mixed-mode Ultra Scaled Integrated Circuits (T-MUSIC) effort. This effort ...
