AMPLIFIER: Electronic instrument that converts the signal into one of greater intensity, because when the waves travel long distances, they arrive at their destination attenuated.


ANGULAR DISTANCE: It is a distance between two objects, measured in radians, that is, the distance between them must be visualized as the distance traveled that would draw an arc of circumference.


BANDWIDTH: Amount of information received every second according to a signal produced.


CONDUCTOR: It is a material that allows the passage of electric current through it, that is, it allows electrons to travel through it. Therefore, it is used to transport supply current or communications signals as the case may be.


CONNECTIVITY: It is the confirmation that a link or communication can be made between two devices, for this, both the sender and the receiver must be on, handle


COSMIC NOISE: It is the electrical noise generated outside the Earth’s atmosphere, also known as background noise, or galactic radio frequency , was discovered by chance in 1965 by Arno Penzias and Robert Wilson.


FILTER: Electronic instrument that allows to differentiate a transmission frequency from the rest of the signals and its main function is to separate the one in which you are interested, from the rest that travels with it in the carrier (or main wave).


FREQUENCY MODULATED: Angular modulation technique that allows the transmission of diverse information through carrier waves varying their frequency.


IMAGE QUALITY: It is the perception of the representation in pixels on a screen of the received signal of the multimedia type, be it image or video. This depends both on the recording format of the same, the resolution of the device with which it was captured and the efficiency of its transmission and reception, as well as the quality of the video handling of the receiving device (video card section ).


INSULATOR: It is a material that does not allow the passage of electric current, usually used to protect from a discharge. In the case of transmission cables in telecommunications, these are used to isolate the conductor cable from the signal, external noise and the effects of temperature, as well as chemical damage, depending on the type of insulation used.


INTERFEROMETER: It is a device that combines the light of two or more telescopes, so that astronomers can select the details of the object under observation, for which mirrors or antennas are used which measure hundreds of meters in diameter. Also, an interferometer is an instrument that, making use of light interference, measures distance, refractive index, length, etc., of waves.


MEDIUM FREQUENCY: Electromagnetic spectrum band used in certain frequencies less than 300 Khz for use in telecommunications. PHOTOVOLTAIC CELL: It is an electronic device that has the ability to absorb light energy and react to it, being able to convert it into electrical energy, that is, when the light rays affect the photovoltaic cell, the material reacts if the amount of light is sufficient, organizing its particles, allowing the passage of electrons so that this current can be collected through conductive cables connected to it and this energy can be stored and used in homes, cars, toys, etc.


POWER: According to physics, it is the result of the intensity times the cross-sectional area of ​​the wave. The energy transmitted in a time interval is equal to the power times the time. Power is measured in W(Watts) and energy in J (Joules). Said colloquially, it is the intensity with which a wave is transmitted in the medium that conducts it.


RADIO ASTRONOMY: Study of the stars based on the electromagnetic waves emitted by them.


RADIO SOURCES: It is an object in outer space that emits electromagnetic radiation in the radio frequency spectrum. This is generated by hot gasses, electrons moving in magnetic fields, and wavelengths being emitted by atoms and molecules in space.


SEMICONDUCTOR: It is a material that allows the passage of electric current in an intermediate way, most electronic devices are formed by semiconductor materials, one of the most popular is Silicon. similar frequencies, in addition to using the same type of coding and communication protocols.

THERMIONIC VALVE: It is also known as electronic valve. It is an electronic component used to modify or amplify an electrical signal by controlling the movement of electrons in an empty space or in the presence of specific gases.


VALVE: Electric bulb of characteristics that performs various functions in radiotelephony apparatus.
