Nt1310 Unit 7 Exercise 1
Crosstalk- unwanted signals in a communication channel (as in a telephone, radio, or computer) caused by transference of energy from another circuit (as by leakage or coupling)
Waveguides- a device (as a duct, coaxial cable, or glass fiber) designed to confine and direct the propagation of electromagnetic waves
FTTH- the installation and use of optical fiber from a central point directly to individual buildings such as residences, apartment buildings and businesses to provide unprecedented high-speed Internet access.
Simplex- allowing telecommunication in only one direction
Half-Duplex- the transmission of data in just one direction at a time
Full-Duplex- Refers to the transmission of data in two directions simultaneously
Photo-diode- A light-activated semiconductor device that allows current to flow in only one direction.
Amplitude Modulation- modulation of the amplitude of a radio carrier wave in accordance with the strength of the audio or other signal
Analog Transmission- 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
Digital Transmission- Transmission of video, voice and other data first encoded into binary values and then transmitted as electrical pulses.
Sample Rate- The number of times an analog signal is measured (sampled) per second
Electromagnetic waves- a wave produced by the acceleration of an electric charge and propagated by the periodic variation of intensities of, usually, perpendicular electric and magnetic fields.
Refraction- deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different
Medium- a substance regarded as the means of transmission of a force or effect
Total Internal Reflection- the complete reflection of a light ray at the boundary of two media, when the
