Amplitude-shift keying
Amplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave.

Automatic terminal information service
Automatic terminal information service, or ATIS, is a continuous broadcast of recorded aeronautical information in busier terminal areas, i.e. airports and their immediate surroundings.

Binary number
In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically 0 (zero) and 1 (one).

Carrier wave
In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information.

Computer
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming.

Continuous wave
A continuous wave or continuous waveform (CW) is an electromagnetic wave of constant amplitude and frequency, almost always a sine wave, that for mathematical analysis is considered to be of infinite duration.

Data
Data is a set of values of qualitative or quantitative variables.

Digital data
Digital data, in information theory and information systems, is the discrete, discontinuous representation of information or works.

Frequency-shift keying
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal.

Infrared Data Association
The Infrared Data Association (IrDA) is an industry-driven interest group that was founded in 1993 by around 50 companies.

ISM band
The industrial, scientific and medical (ISM) radio bands are radio bands (portions of the radio spectrum) reserved internationally for the use of radio frequency (RF) energy for industrial, scientific and medical purposes other than telecommunications.

Line code
Some signals are more prone to error than others when conveyed over a communication channel as the physics of the communication or storage medium constrains the repertoire of signals that can be used reliably.
New!!: On-off keying and Line code · See more »
Modulation
In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.

Morse code
Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment.

Murata Manufacturing
is a Japanese manufacturer of electronic components, based in Nagaokakyo, Kyoto.

Optical communication
Optical communication, also known as optical telecommunication, is communication at a distance using light to carry information.

Pilot-controlled lighting
Pilot-controlled lighting (PCL), also known as aircraft radio control of aerodrome lighting (ARCAL) or pilot-activated lighting (PAL), is a system which allows aircraft pilots to control the lighting of an airport or airfield's approach lights, edge lights, and taxiways via radio.

Radio frequency
Radio frequency (RF) refers to oscillatory change in voltage or current in a circuit, waveguide or transmission line in the range extending from around twenty thousand times per second to around three hundred billion times per second, roughly between the upper limit of audio and the lower limit of infrared.

Regenerative circuit
A regenerative circuit is an amplifier circuit that employs positive feedback (also known as regeneration); some of the output of the amplifying device is applied to its input without phase inversion, which reinforces the signal, increasing the amplification.

Spectral efficiency
Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system.
New!!: On-off keying and Spectral efficiency · See more »
Superheterodyne receiver
A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency.

Unipolar encoding
Unipolar encoding is a line code.
