  2. Impedance analogy - Wikipedia

    en.wikipedia.org/wiki/Impedance_analogy

    The circuit diagram shows an impedance analogy model of the human ear. The ear canal section is followed by a transformer representing the eardrum. The eardrum is the transducer between the acoustic waves in air in the ear canal and the mechanical vibrations in the bones of the middle ear.

  3. List of free electronics circuit simulators - Wikipedia

    en.wikipedia.org/wiki/List_of_free_electronics...

    List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.

  4. Four-wire circuit - Wikipedia

    en.wikipedia.org/wiki/Four-wire_circuit

    In telecommunications, a four-wire circuit is a two-way circuit using two paths so arranged that the respective signals are transmitted in one direction only by one path and in the other direction by the other path.

  5. 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.

  6. Mobility analogy - Wikipedia

    en.wikipedia.org/wiki/Mobility_analogy

    The mobility analogy, also called admittance analogy or Firestone analogy, is a method of representing a mechanical system by an analogous electrical system.The advantage of doing this is that there is a large body of theory and analysis techniques concerning complex electrical systems, especially in the field of filters. [1]

  7. Analog signal processing - Wikipedia

    en.wikipedia.org/wiki/Analog_signal_processing

    Analog signal processing is a type of signal processing conducted on continuous analog signals by some analog means (as opposed to the discrete digital signal processing where the signal processing is carried out by a digital process). "Analog" indicates something that is mathematically represented as a set of continuous values.

  8. Gear stick - Wikipedia

    en.wikipedia.org/wiki/Gear_stick

    A standard 5-speed shift pattern (on a Peugeot 206 knob). A gear stick (rarely spelled gearstick), [1] [2] gear lever (both UK English), gearshift or shifter (both U.S. English), more formally known as a transmission lever, is a metal lever attached to the transmission of an automobile.

  9. Analogue switch - Wikipedia

    en.wikipedia.org/wiki/Analogue_switch

    An analogue switch: Maxim MAX313. An analogue switch, also called a bilateral switch, is an electronic component that behaves in a similar way to a relay, but has no moving parts. The switching element is normally a pair of MOSFET transistors, one an N-channel device, the other a P-channel device. The device can conduct analog or digital ...
