  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. 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 ...

  4. 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 ...

  5. 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.

  6. Eye pattern - Wikipedia

    en.wikipedia.org/wiki/Eye_pattern

    Eye pattern of a 1.25 Gbit/s NRZ signal through a lossy channel. As high frequency losses increase the overall shape of the eye gradually degrades into a sinusoid (once higher frequency harmonics of the data has been eliminated, all that remains is the fundamental) and decreases in amplitude.

  7. Polarization (waves) - Wikipedia

    en.wikipedia.org/wiki/Polarization_(waves)

    Polarized light can be produced by passing unpolarized light through a polarizer, which allows waves of only one polarization to pass through. The most common optical materials do not affect the polarization of light, but some materials—those that exhibit birefringence , dichroism , or optical activity —affect light differently depending on ...

  8. Multiple patterning - Wikipedia

    en.wikipedia.org/wiki/Multiple_patterning

    A more serious concern was the effect of feature-to-feature positioning errors (overlay). Consequently, the self-aligned sidewall imaging approach (described below) has succeeded this approach. A "brute force" approach for patterning trenches involves a sequence of (at least) two separate exposures and etchings of independent patterns into the ...

  9. Consumer Electronics Control - Wikipedia

    en.wikipedia.org/wiki/Consumer_Electronics_Control

    Consumer Electronics Control (CEC) is a feature of HDMI designed to control HDMI connected devices [1] [2] by using only one remote controller; so, individual CEC enabled devices can command and control each other without user intervention, for up to 15 devices.
