  2. Passthrough (electronics) - Wikipedia

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

    VCRs, DVD recorders, etc. act as a "pass-through" for composite video and S-video, though sometimes they act as an RF modulator for use on Channel 3. Tape monitor features allow an AV receiver (sometime the recording device itself) to act as a "pass-through" for audio.

  3. Analog passthrough - Wikipedia

    en.wikipedia.org/wiki/Analog_passthrough

    Analog passthrough is a feature found on some digital-to-analog television converter boxes. Boxes without the analog passthrough feature only allow older, analog-only TVs to view digital TV. Those with analog pass-through allow both digital and analog television to be viewed on older TVs.

  4. Polar modulation - Wikipedia

    en.wikipedia.org/wiki/Polar_modulation

    Polar modulation was originally developed by Thomas Edison in his 1874 quadruplex telegraph – this allowed 4 signals to be sent along a pair of lines, 2 in each direction. Sending a signal in each direction had already been accomplished earlier, and Edison found that by combining amplitude and phase modulation (i.e., by polar modulation), he ...

  5. List of satellite pass predictors - Wikipedia

    en.wikipedia.org/wiki/List_of_satellite_pass...

    Pass Predictions API by Re CAE provides a live objects catalog and pass predictions. It features a filtering system for the catalog to only display objects with matching name or ID. The pass predictions generates, among other things, the time window, minimum elevation and the apparent brightness of the object in the sky.

  6. Line code - Wikipedia

    en.wikipedia.org/wiki/Line_code

    After line coding, the signal is put through a physical communication channel, either a transmission medium or data storage medium. [3] [4] The most common physical channels are: the line-coded signal can directly be put on a transmission line, in the form of variations of the voltage or current (often using differential signaling).

  7. Passthrough device - Wikipedia

    en.wikipedia.org/wiki/Passthrough_device

    A passthrough device is a device used in conjunction with a computer to reprogram vehicle control modules through the OBD-II/CANbus port. [1] Each manufacturer has their own type, but SAE International standardized the J-2534 universal requirements in 2004, requiring all manufacturers to allow vehicles sold in the United States of America and Europe to accept powertrain reprogramming through ...

    Low-profile quad flat-package : 1.4 mm high, varying sized and pins on all four sides; Plastic quad flat-pack , a square with pins on all four sides, 44 or more pins; Ceramic quad flat-pack : similar to PQFP; Metric quad flat-pack : a QFP package with metric pin distribution; Thin quad flat-pack , a thinner version of LQFP

  9. Polar orbit - Wikipedia

    en.wikipedia.org/wiki/Polar_orbit

    Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. [2] The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a Sun-synchronous orbit, where each successive orbital pass occurs at the same local time of ...
