2. Active cable - Wikipedia

   en.wikipedia.org/wiki/Active_cable

   Unlike passive cables, which can suffer from data degradation due to issues such as attenuation, crosstalk, and group velocity distortion, active cables contain one or more integrated circuits to address these problems. This active boosting allows cables to be more compact, thinner, and longer, and to transmit data faster than passive cables.

   It can also carry audio, USB, and other forms of data. DisplayPort is backward compatible with other interfaces such as HDMI and DVI through the use of active or passive adapters. Male Mini DisplayPort plug Mini DisplayPort: Proposed alternative to HDMI, used with computer displays: (VGA, DVI) Apple Inc.'s successor to their own Mini-DVI.

   Active Audio Distribution Amplifier AudioPressBox APB-224 C 1:2 Stereo Audio Distribution Amplifier - side with output. In electronics, a distribution amplifier, or simply distribution amp or DA, is a device that accepts a single input signal and provides this same signal to multiple isolated outputs.

   The use of passive cables is possible when both devices support the standard, e.g., when connecting to superMHL, USB Type-C, and MHL-enabled HDMI, otherwise, an active cable adapter is necessary to connect to standard HDMI devices. [24]

7. Powered speakers - Wikipedia

   en.wikipedia.org/wiki/Powered_speakers

   An active full-range loudspeaker. Powered speakers, also known as self-powered speakers and active speakers, are loudspeakers that have built-in amplifiers.Powered speakers are used in a range of settings, including in sound reinforcement systems (used at live music concerts), both for the main speakers facing the audience and the monitor speakers facing the performers; by DJs performing at ...

8. Intermodulation - Wikipedia

   en.wikipedia.org/wiki/Intermodulation

   Passive intermodulation (PIM), however, occurs in passive devices (which may include cables, antennas etc.) that are subjected to two or more high power tones. [4] The PIM product is the result of the two (or more) high power tones mixing at device nonlinearities such as junctions of dissimilar metals or metal-oxide junctions, such as loose ...

9. 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 ...
