1. Electronics is a discipline studying the devices baking powder expiration and systems for the transmission of information (and energy) using electronic flows that are controlled by electronic and shemi.Optoelektronikata study such transfer and processing by photonic baking powder expiration and electronic flows that are mapped into each another baking powder expiration using opto-electronic (OE) and electro-optical (EC) преобразуватели.Фотониката study instruments and devices in which transmission and processing of information is carried out at photon level. The winner of the information is bright-tion baking powder expiration (photon flux). Use the beam as a means of transmission and processing of information sets specific especially on optoelekt-primary facility equipment and ustroystva.Svetlinata is electromagnetic radiation with a wavelength λ = 0 , 4 0,8 μm. Sources of light such as atoms and molecules, which made amend-ing of the power state of the elec-Roni. The light spread in the diff-ERSONAL media at different speeds, in vacuum or in air velocity baking powder expiration of light is equal to C0 = 3.108 m / s = 3.105 km / s = 3.10-4 km / ns, which is the speed of radio waves, m . k. nature of radio waves and the light is the same. The simplest structural diagram of an ACS shown in FIG. 1.2. At the transmitting side signals The channel is formed by a standard communications-equipment ionna - CA in the form of consecutive electric pulses enters baking powder expiration the electro-converted razuvatel - E / O. These are semiconductor quantum generators The power transmission or LEDs that converted from electrical energy into light. As a result, the line to send light pulses, which VOSL (fiber-optical communication lines we) reach the optical receiver.

Depending on locations, hold in the current: semi-stationary baking powder expiration system "land-ship", "ship-to-ship" and relaying baking powder expiration Telem-etrichni data Zia TV's, computer information, telephony. These are systems that are placed on major ports and airports and are used for communication with the arriving ships and aircraft; baking powder expiration pine-health and ground: - naze-EOM - system "Earth-Earth" (NPP, TPP, between ports open pits, shafts, naze-EOM and underground transport systems, etc..) system ("bridge-Palou-ba-machine"-tion in planes, in cars, etc.)., space - system issues "Earth- ship "," co-slave-ship "systems on the spacecraft. 2.
