Microelectromechanical system oscillator

Micro-electro-mechanical system (MEMS) oscillators are timing devices that are very stable reference frequencies, which may generate measure time. This reference frequency can be used to sequence electronic systems, manage data transfer Define radio frequencies, and measuring elapsed time. The core technologies used in MEMS oscillators are in development since the mid-1960s, but only sufficiently advanced for defining

Intel readies chip to rival NVIDIA for machine learning

Intel readies chip After leaving his own GPU supercomputers, machine learning, and video games in 2009, Intel has returned to the market with a new 72-core Xeon Phi, to compete with the growing portfolio of NVIDIA’s GPUs. The Xeon Phi “Knights Landing” chip, announced at the International Supercomputing Conference in Frankfurt, Germany last week, Intel’s most powerful and expensive chip-to-date

Channel communications network

Telecommunications and computer networks, a communication channel or channel, refers either a physical transmission medium such as a wire or a logical connection on a multiplexed medium, such as a radio channel. A channel is used to bring an information signal, e.g., a digital bit stream, of one or more stations (or transmitters) one or more recipients. One channel has a certain capacity for the transmission of information

Carrier wave

In the telecommunications sector, a carrier, carrier signal, or single carrier, is a waveform (generally sinusoidal) which is modulated (adapted) to an input signal for the purpose of information transmission. This carrier wave is usually a much higher frequency than the input signal. The aim of the carrier usually refers to the information through space as electromagnetic waves (such as radio) or to

WiMAX (Worldwide Interoperability for Microwave Access) is a family of wireless communication standards primarily designed to provide 30 to 40 megabits per second data rates, to give the 2011 update to 1 Gbit / s for fixed stations. The name “WiMAX” was created by the its Forum, which was established in June 2001 to promote conformance and interoperability of the standard. The forum describes it as “a

Fiber Bragg grating

A fiber Bragg grating (FBG) is a kind of distributed Bragg reflector constructed in a short segment of optical fiber which reflect specific wavelengths of light and transmits all others. This is achieved by a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths

PROFINET Device Classification

PROFINET IO devices classifies into three types; IO controller, IO devices and IO supervisors. IO controllers are devices that implement an automation program. Controllers, functionally similar to a Profibus Master Class 1, to exchange data with IO devices. IO devices are distributed sensor / actuator devices connected to the IO controller over Ethernet. In terms Profibus, IO devices are comparable with PROFIBUS slaves

Analog signal

An analog signal has a theoretically infinite resolution. In practice, an analogue signal is subject to electronic noise and distortion introduced by communication channel sand signal processing operations, which progressively can degrade the signal-to-noise ratio (SNR). By contrast, digital signals, a finite resolution. Converting an analog signal into digital form, introduces a constant low-level noise referred to as

XLR connector

The XLR connector is a style of electrical connector to be found primarily on the professional audio, video and stage lighting equipment. The connections are circular in shape and may have between 3 and 7. They are most commonly associated with balanced audio interconnection, including AES3 digital audio, but are also used for the lighting control, low-voltage power supplies, and other applications. XLR connectors are

Auto negotiation

Auto negotiation is an Ethernet procedure by which two connected devices choose common transmission parameters such as speed, duplex mode, and flow control. In this process, the connected devices first share their capabilities with respect to these parameters and then choose the highest performance transmission mode they both support. In the OSI model, auto negotiation is in the physical layer. Ethernet over twisted pair
