Exempel på hur du använder TELEGRAPHY i en mening

• In the past, telecommunications included telegraphy available through Canadian Pacific and Canadian National.
• Electrical telegraphy is a point-to-point text messaging system, primarily used from the 1840s until the late 20th century.
• Braun shared the 1909 Nobel Prize in Physics with Guglielmo Marconi "for their contributions to the development of wireless telegraphy".
• Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy.
• The US Navy Department successfully tested printing telegraphy between an airplane and ground radio station in 1922.
• Semaphore is the use of an apparatus with telegraphy to create a visual signal transmitted over long-distances.
• Electrical telegraphy had been developed decades earlier in the late 1830s and 1840s, then using simpler Morse key equipment and telegraph operators.
• Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using cables.
• The baud unit is named after Émile Baudot, the inventor of the Baudot code for telegraphy, and is represented according to the rules for SI units.
• In telegraphy, frequency-exchange signaling or two-source frequency keying is frequency-change signaling in which the change from one significant condition to another is accompanied by decay in amplitude of one or more frequencies and by buildup in amplitude of one or more other frequencies.
• Time-division multiplexing was first developed for applications in telegraphy to route multiple transmissions simultaneously over a single transmission line.
• Paul Julius Reuter (born Israel Beer Josaphat; 21 July 1816 – 25 February 1899), later ennobled as Freiherr von Reuter (Baron von Reuter), was a German-born British entrepreneur who was a pioneer of telegraphy and news reporting.
• The first submarine communications cables were laid beginning in the 1850s and carried telegraphy traffic, establishing the first instant telecommunications links between continents, such as the first transatlantic telegraph cable which became operational on 16 August 1858.
• A devastating defeat for the Imperial Russian Navy, the battle was the only decisive engagement ever fought between modern steel battleship fleets and the first in which wireless telegraphy (radio) played a critically important role.
• He is credited with early developments in several fields, such as incandescent lighting and telegraphy.
• A recommendation was made for the establishment of a new agency that would regulate all interstate and foreign communication by wire and radio, telegraphy, telephone and broadcast.
• However, Wheatstone is best known for his contributions in the development of the Wheatstone bridge, originally invented by Samuel Hunter Christie, which is used to measure an unknown electrical resistance, and as a major figure in the development of telegraphy.
• Radio communication was by wireless telegraphy; at the sending end, an operator tapped on a switch which caused the radio transmitter to produce a series of pulses of radio waves which spelled out text messages in Morse code.
• Optical telegraphy dates from ancient times, in the form of hydraulic telegraphs, torches (as used by ancient cultures since the discovery of fire) and smoke signals.
• A telegraph key, clacker, tapper or morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system.
