Philips MCI500H/05 사용자 설명서

36

Analog sound can only be transmitted through 

two channels.
Duplex (half/full)

Full duplex is the ability to send and 

• 

receive data simultaneously. Duplex is 

synonymous with full duplex. Example: 

when a modem operates in full-duplex 

mode, it can transmit data in two 

directions simultaneously. In half-duplex 

mode it can transmit data in two 

directions, but not simultaneously.

E

Eco (Eco Standby)

Eco Standby is the most ‘economic’ mode of 

the MCi500H and consumes less than 1W. It is 

‘economic’ and environmentally friendly to use 

this mode during longer times of non-usage of 

the MCi500H.
EQ (Equalizer)

A class of electronic filter circuits designed 

to augment or adjust electronic or acoustic 

systems. Equalizers can be fixed or adjustable, 

active or passive. Many equalizers divide the 

spectrum into 3 to 12 bands. This allows each 

section to be either increased or decreased in 

amplitude without changing the response of 

the rest.

F

Fidelity

A term used to describe the accuracy of 

recording, reproduction, or general quality of 

audio processing. “High Fidelity” (Hi-Fi) is the 

goal of every designer.
FM (Frequency Modulation)

In radio broadcasting: a method of modulation 

in which the frequency of the carrier voltage 

is varied with the frequency of the modulation 

voltage.
Frequency

The property or condition of occurring at 

frequent intervals. In sound, this simply refers 

Coaxial

A single copper conductor, surrounded with 

a layer of insulation, covered by a surrounding 

copper shield and finally, an insulating jacket. 

An unbalanced transmission line with constant 

impedance. In audio, this type is commonly 

used for low level, line signals terminated in 

RCA connectors.

Compression

In audio terms, this is a process of temporarily 

or permanently reducing audio data for more 

efficient storage or transmission. A temporary 

reduction in file size is called ‘non-lossy’ 

compression, and no information is lost. A 

permanent reduction in file size (such as with 

MP3 files) is called ‘lossy’ compression, and 

involves discarding unnecessary information 

which is irretrievably lost.

D

dB (Decibel)

A unit of measure used to express relative 

difference in power or intensity of sound.
DC (direct current)

Direct current or continuous current is 

the constant flow of electric charge. This is 

typically in a conductor such as a wire. In 

direct current, the electric charges flow in 

the same direction, distinguishing it from AC 

(alternating current).
DHCP

DHCP stands for Dynamic Host Configuration 

Protocol. It is a protocol for assigning dynamic 

IP addresses to devices on a network. 
Digital

A method to encode information using a 

binary code of 0s and 1s. Many wireless 

phones and networks use digital technology.
Digital Audio

Digital Audio is a sound signal that has been 

converted into numerical values. Digital sound 

can be transmitted through multiple channels.
