Part I Vocabulary
1. Сопоставьте слово с его определением (10x1):
wireless – communicating without connecting wires or other material contacts
radiation – the emission or transfer of radiant energy as particles, electromagnetic waves, sound, etc;.
oscillation – regular fluctuation in value, position, or state about a mean value,
frequency – the number of times that a periodic function or vibration repeats itself in a specified time.
emission – energy, in the form of heat, light, radio waves, etc., emitted from a source;
amplification – the increase in strength of an electrical signal by means of an amplifier;
induction – the process by which electrical or magnetic properties are transferred, transmission – the act or process of sending a message, picture, or other information from one location to one or more other locations by means of radio waves, electrical signals, light signals, etc;
vacuum tube – an evacuated electron tube containing a cathode, anode, and, usually, one or more additional control electrodes.
receiver – the part of a telephone containing the earpiece and mouthpiece that is held by the telephone user
harmonic – a component of a periodic quantity, such as a musical tone, with a frequency that is an integral multiple of the fundamental frequency
amplifier – an electronic device used to increase the strength of the signal fed into it
relay – a combination of a receiver and transmitter designed to receive radio signals and retransmit them, in order to extend their range
transistor – a semiconductor device, having three or more terminals attached to electrode regions, in which current flowing between two electrodes is controlled by a voltage or current applied to one or more specified electrodes.
modulation – the act or process of superimposing the amplitude, frequency, phase, etc., of a wave or signal onto another wave (the carrier wave) or signal or onto an electron beam
conductor – a substance, body, or system that conducts electricity, heat, etc.
semiconductor – a substance, such as germanium or silicon, that has an electrical conductivity that increases with temperature and is intermediate between that of a metal and an insulator;
current – a flow of electric charge through a conductor (the rate of flow of this charge); it is measured in amperes
input – the signal or current fed into a component or circuit
microchip – a small piece of semiconductor material carrying many integrated circuits;
integrate – to make or be made into a whole; incorporate or be incorporated;
diode – a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current;
fluctuation – change, especially continuous and between one level or thing and another:
range – the distance within which you can see, hear.
deviation – different direction
broadcast – to send out a programme on television or radio:
subtract – to remove a number from another number:
satellite – an artificial object sent up into space to travel round the earth, used for collecting information or communicating by radio, television, etc:
application –a way in which something can be used
approximation – a guess of a number that is not exact
bandwidth – the range of frequencies
beam – a light that shines from a bright object
cell – a small part of something
define−explain the meaning
devote – to give all to something or somebody
domain−an area of interest or control
extensive− covering the large area
flawlessly – without mistakes
implement – put into operation
invention – something which has never been made before
latency – the amount of time it takes a packet to travel from source to destination
robust – strong and unlikely to break
solution – the answer to a problem
