Terminology
Words to consider when further researching about analog and digital signals or physics in general.
Meanings extracted from: http://www.oxforddictionaries.com/
Amplification
The process of increasing the volume of sound, especially using an amplifier
Analog
Relating to or using signals or information represented by a continuously variable physical quantity such as spacial position, voltage, etc
Attenuation
The reduction of the amplitude of a signal, electric current, or other oscillation
Automation
The use or introduction of automatic equipment in a manufacturing or other process or facility
Bandwidth
A range of frequencies within a given band, in particular that used for transmitting a signal
Circuit

Digital
Expressed as series of the digits 0 and 1, typically represented by values of a physical quantity such as voltage
Demodulation
Extract or separate (a modulating signal) from its carrier
Modulation
Alteration of the amplitude or frequency of an electromagnetic wave or other oscillation in accordance with the variations of a second signal
Noise
Irregular fluctuations that accompany a transmitted electrical signal but are not part of it and tend to obscure it
Signal
An electrical impulse or radio wave transmitted or received
RTL
Resistor Transistor Logic
DTL
Diode Transistor Logic
TTL
Transistor Transistor Logic
PBX (Private Branch Exchange)
A system that connects telephone extensions to the Public Switched Telephone Network and provides internal communication for a business.
