Introduction to Electronics Communication Flashcards
What are the types of Communication
Verbal, Non Verbal, Print, Electronic Processes
What is the chain system of communication by blocks based on Ma’am Joyce Powerpoint
Information to Transmitter to Medium to Receiver
Electric Component that Converts an information to an electronic signal
Transmitter
A form of Channel Impairment, an unwanted signal that interferes with the communications during the channeling of the information
Noise
An electronic components that consist of oscillators, amplifiers, tuned circuits, filters, modulators, frequency mixers, frequency synthesizers, and such
Transmitter
What are the 3 types of Channel
Electrical Conductors, Optical Media, Free Space
A simplest type of channel that uses a pair of wires like coaxial cable for tv signals or twisted-pair cable for LAN connections
Electrical Conductors
Type of Medium/Channel that uses fiber optic cable that carries message thru light waves, most used in internet connection
Optical Media
Type of Medium/Channel that are mostly used by radio and mostly carries electromagnetic signals to travel over a very long distance
Free Space
A collection of electronic component that consist of oscillators, amplifiers, mixers, tuned circuits, demodulator/detector that recovers original intelligence/information from the modulated carrier
Receiver
Information source = Source Encoder - Channel Encoder - Modulator = Channel = Demodulator/Detector - Channel Decoder - Source Decoder = Information Sink
Communications System
A electronic component that both function as Transmitter and Receiver
Transceiver
3 forms of Channel Impairments
Attenuation, Noise, Distortion
Form of Channel Impairments thru the loss of signal strength (lowering of volume)
Attenuation
A channel impairment that alters the basic waveform
Distortion
Type of Distortion that changes the amplitude or phase without adding new frequencies.
Linear Distortion
Type of Distortion when a new frequency is added to the waveform causing an slight interference
Non-Linear Distortion
A type of signal that is continuous change of voltage/current
Analog signal
A type of signal that is not continuous but increment changes like a step
Digital Signal
A simplest way of Communication that only allows one way of communication(only receive/ only transmit) example: television, Radio
Simplex
A form of two-way communication that allows both connection to transmit and receive but only one at a time
Half Duplex
A form of two-way communication that allows both connection to transmit and receive simultaneously
Full Duplex
A transmitting technique that converts information/intelligence into a more compatible form for the medium/channel
Modulation
A transmitting technique that allows more than one signal to be transmitted on the same medium
Multiplexing
