  2. Attenuator (electronics) - Wikipedia

    en.wikipedia.org/wiki/Attenuator_(electronics)

    An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...

    S/PDIF is an audio-only format carried over electrical coaxial cable (with RCA jacks) or optical fibre . Note that there are no differences in the signals transmitted over optical or coaxial S/PDIF connectors—both carry exactly the same information. Selection of one over the other rests mainly on the availability of appropriate connectors on ...

  4. Π pad - Wikipedia

    en.wikipedia.org/wiki/Π_pad

    A Π-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A Π pad can be viewed as being two L sections back-to-back as ...

    The GMSL link provides camera power, camera control, fault reporting and video transport across a single, coaxial cable. ADAS systems are considered safety-critical systems, and typically have an Automotive Safety Integrity Level (ASIL) rating, specified according to the ISO 26262 standard. GMSL devices have built-in fault detection and ...

    Some head units have built-in stereo amplifiers. Other car audio systems use a separate stand-alone amplifier. Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit. Coaxial speakers: These are the most common type of car speakers and are often factory-installed.

  7. Optical attenuator - Wikipedia

    en.wikipedia.org/wiki/Optical_attenuator

    Built-in variable optical attenuators may be either manually or electrically controlled. A manual device is useful for one-time set up of a system, and is a near-equivalent to a fixed attenuator, and may be referred to as an "adjustable attenuator". In contrast, an electrically controlled attenuator can provide adaptive power optimization.

  9. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.
