  2. Analog transmission - Wikipedia

    en.wikipedia.org/wiki/Analog_transmission

    Analog transmission is a transmission method of conveying information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that information. It could be the transfer of an analog signal, using an analog modulation method such as frequency modulation (FM) or amplitude modulation (AM), or no ...

  3. Signal transmission - Wikipedia

    en.wikipedia.org/wiki/Signal_transmission

    Antenna used for transmission of radio signals. In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. [1] [2]

  4. Encoding/decoding model of communication - Wikipedia

    en.wikipedia.org/.../decoding_model_of_communication

    As the original model makes all media institutions encode messages in the dominant-hegemonic manner, [3] Ross [14] takes a step further and 'allow' media institutions to encode texts according to the oppositional or negotiated framework. Thus, media texts in both Hall's versions can be dominant-hegemonic (Hall's assumed mode), partly critical ...

  5. Source–message–channel–receiver model of communication

    en.wikipedia.org/wiki/Source–message–channel...

    For example, as a linear transmission model, it does not include the discussion of feedback loops found in many later models. Another common objection is that the SMCR model fails to take noise and other barriers to communication seriously and simply assumes that communication attempts are successful.

  6. Models of communication - Wikipedia

    en.wikipedia.org/wiki/Models_of_communication

    Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.

  7. Analogue electronics - Wikipedia

    en.wikipedia.org/wiki/Analogue_electronics

    Analogue electronics (American English: analog electronics) are electronic systems with a continuously variable signal, in contrast to digital electronics where signals usually take only two levels. The term analogue describes the proportional relationship between a signal and a voltage or current that represents the signal.

  8. Analog signal - Wikipedia

    en.wikipedia.org/wiki/Analog_signal

    An analog signal uses some property of the medium to convey the signal's information. For example, an aneroid barometer uses rotary position as the signal to convey pressure information. In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information. [citation needed]

  9. Biasing - Wikipedia

    en.wikipedia.org/wiki/Biasing

    A graphical representation of the current and voltage properties of a transistor; the bias is selected so that the operating point permits maximum signal amplitude without distortion. In electronics , biasing is the setting of DC ( direct current ) operating conditions (current and voltage) of an electronic component that processes time-varying ...
