A
Means…
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.
ASI
Asynchronous Serial Interface. A streaming data interface
which often carries an MPEG Transport Stream.
An ASI signal can carry one or multiple SD, HD or audio
programs that are already compressed, not like an
uncompressed SD-SDI (270Mbs) or HD-SDI (1.45Gbs). An ASI
signal can carry varying amounts of data but is always padded
to run at a fixed line rate of 270 Mb/s.
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…
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.
Decoder
Processor in a video receiver that converts digital video data to
analogue signals for replay on analogue monitors; or in certain
cases a software decoder, a program that decodes digital data
for replay on the PC (decompression etc).
Demodulate
To recover the information originally impressed on the radio
