These examples are programmatically compiled from many online sources As an instance present use with the term 'audio.' Any viewpoints expressed inside the examples never depict All those of Merriam-Webster or its editors. Deliver us comments about these examples.
The direction of your beam reveals the object's spot. Considering that radio waves travel at a constant speed close to the pace of light, by measuring the short time hold off amongst the outgoing pulse plus the obtained "echo", the range for the goal is often calculated. The targets will often be shown graphically on the map Show called a radar display. Doppler radar can evaluate a transferring item's velocity, by measuring the improve in frequency in the return radio waves mainly because of the Doppler influence.[131]
Be cautious never to get caught up in the small print. There are no great speakers. Particular flavor, desire, and listening patterns will matter much more within your choice.
Cellphone – a portable wireless phone that may be linked to the phone network by radio signals exchanged with a local antenna at a mobile base station (mobile tower).[87] The company place protected with the service provider is divided into little geographical places named "cells", Just about every served by a independent foundation station antenna and multichannel transceiver. The many mobile phones in a mobile converse with this antenna on separate frequency channels, assigned from a standard pool of frequencies. The purpose of mobile Corporation should be to preserve radio bandwidth by frequency reuse. Lower power transmitters are applied so the radio waves used in a mobile will not journey significantly beyond the cell, permitting the same frequencies to be reused in geographically separated cells. Every time a user carrying a cellphone crosses from just one mobile to another, his mobile phone is automatically "handed off" seamlessly to the new antenna and assigned new frequencies.
Commercial free music curated by top-edge DJs in addition exceptional information from your favorite artists and mounting stars.
Medium-voltage distribution lines can also use 1 or 2 shield wires, or may possess the grounded conductor strung underneath the phase conductors to deliver some evaluate of security against tall automobiles or machines touching the energized line, along with to deliver a neutral line in Wye wired systems.
Phased-array radar – a radar set that works by using a phased array, a computer-managed antenna that will steer the radar beam swiftly to position in various directions without transferring the antenna.
By obtaining the indicators from a minimum of 4 satellites a GPS receiver can determine its position on this see this page planet by comparing the arrival time of your radio indicators. Considering that Just about every satellite's situation is known exactly at any supplied time, through the hold off the position in the receiver is often calculated by a microprocessor in the receiver. The placement is often exhibited as latitude and longitude, or being a marker on an Digital map. GPS receivers are included in Nearly all cellphones and in motor vehicles like automobiles, plane, and ships, and so are utilized to guide drones, missiles, cruise missiles, and perhaps artillery shells for their goal, and recommended you read handheld GPS receivers are made for hikers and also the navy.[145][146]
Since the surrounding air presents fantastic cooling, insulation together extensive passages and enables optical inspection, overhead power lines are frequently the lowest-Value method of power transmission for large quantities of electric Power.
These networks start off with the transformers and conclude with homes, educational institutions, and businesses. Distribution is controlled on the point out degree by PUCs and PSCs, who set the retail rates for electrical energy in Each individual condition.
Despite a marketing campaign by Thomas Edison to market the direct present-day system, businessman George Westinghouse and inventor Nikola Tesla gained the help of electric powered providers with the alternating recent system, which experienced the unique advantage of making it possible for higher voltages being carried lengthy distances and afterwards reworked into reduced voltages for client use [nine].
This warms the area slightly and minimizes the effect of fog and dirt accumulation. The semiconducting glaze also guarantees a more even distribution of voltage alongside the size of the chain of insulator units.
In more info here HVDC systems normally two conductors are carried per line, but in rare instances only one pole of the system is carried over a set of towers.
When transmitting alternating present, bundle conductors also avoid the reduction in ampacity of an individual significant conductor a result of the skin result. A bundle conductor also has lessen reactance, in comparison to an individual conductor.
