Constantin Zablovschi
Constantin Zablovschi (16 July 1882, in Czernowitz – 3 May 1967, in Bucharest) was a Romanian engineer and pioneer in the field of telecommunications. Biography Zablovschi studied at the Faculty of Electrical Engineering at the Technische Hochschule in Charlottenburg (now Technische Universität Berlin) Berlin, and obtained the title of Doctor of Engineering. Upon returning to Romania, he dedicated his career to the development of radio communications, becoming one of the first specialists in this field in the country. He contributed to the establishment of the first radio stations and the development of the national radiocommunication network. Zablovschi was involved in the establishment and development of the Romanian Radio Broadcasting Company. He was also involved in various projects and experiments related to radiocommunications, including establishing the first transcontinental radio links between Romania and other countries. In the 1930s, Zablovschi achieved a remarka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Czernowitz
Chernivtsi (, ; , ;, , see also other names) is a city in southwestern Ukraine on the upper course of the Prut River. Formerly the capital of the historic region of Bukovina, which is now divided between Romania and Ukraine, Chernivtsi serves as the administrative center for the Chernivtsi urban hromada, the Chernivtsi Raion, and the oblast itself. The Chernivtsi population is and the latest census in 2001 was 240,600. The first document that refers to this city dates back to 1408, when Chernivtsi was a town in the region of Moldavia, formerly as a defensive fortification, and became the center of Bukovina in 1488. In 1538, Chernivtsi was under the control of the Principality of Moldavia under Polish suzerainty, later under Ottoman Empire suzerainty, and the Moldavian control lasted for two centuries until 1774, when Austria took control of Bukovina in the aftermath of the Russo-Turkish War. Chernivtsi (known at that time as ) became the center of the Galicia's Buko ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Broadcasting
Radio broadcasting is the broadcasting of audio signal, audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in ''satellite radio'' the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a Radio receiver, broadcast radio receiver (''radio''). Stations are often affiliated with a radio network that provides content in a common radio format, either in broadcast syndication or simulcast, or both. The code, encoding of a radio broadcast depends on whether it uses an analog signal, analog or digital signal. Analog radio broadcasts use one of two types of radio wave modulation: amplitude modulation for AM radio, or frequency modulation for FM radio. Newer, digital radio stations transmit in several different digital audio standards, such as DAB (Digital Audio Broadcas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radio Pioneers
Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scientists From Chernivtsi
A scientist is a person who Scientific method, researches to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different er ...

Radio Frequency
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around to around . This is roughly between the upper limit of audio frequencies that humans can hear (though these are not electromagnetic) and the lower limit of infrared frequencies, and also encompasses the microwave range. These are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves, so they are used in radio technology, among other uses. Different sources specify different upper and lower bounds for the frequency range. Electric current Electric currents that oscillate at radio frequencies (RF currents) have special properties not shared by direct current or lower audio frequency alternating current, such as the 50 or 60 Hz current used in electrical power distribution. * Energy from RF currents in conduct ...
