A
Means…
Analogue
Analog transmission is a transmission method of conveying
voice, data, image, signal or video information using a continuous
signal which varies in amplitude, phase, or some other property in
proportion to that of a variable.
Antenna
An antenna (or aerial) is a transducer designed to radiate or
receive electromagnetic energy (generally RF).
Antenna Bandwidth
The frequency range over which a given antenna will accept
signals.
Antenna Gain
The effectiveness of a directional antenna as compared to a
standard non-directional antenna. It is usually expressed as the
ratio in decibels of standard antenna input power to directional
antenna input power that will produce the same field strength in
the desired direction. For a receiving antenna, the ratio of signal
power values produced at the receiver input terminals is used. The
more directional an antenna is, the higher is its gain.
Attenuation
Power loss resulting from conductor resistance and dielectric loss
within the insulating material used to separate the conductors.
B
Means…
BNC
Bayonet Neill-Concelman – A very common type of RF
connector used for terminating coaxial cable.
Bandwidth
The width of a band of frequencies used for a particular purpose.
C
Means…
COFDM
Coded Orthogonal Frequency Division Multiplexing is a
frequency-division multiplexing (FDM) scheme utilized as a digital
multi-carrier modulation method. A large number of closely-spaced
orthogonal sub-carriers are used to carry data.
D
Means…
D/C
Downconverter. A device which converts microwave frequencies to
UHF frequencies for use in Cobham receivers.
Digital
A digital signal is a discontinuous signal that changes from one
state to another in discrete steps.
Decibel
The standard unit used to express transmission gain or loss and
relative power levels. Also written as dB.
