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
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.
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.
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 ...
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 ...
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 ...
Pass transistor logic often uses fewer transistors, runs faster, and requires less power than the same function implemented with the same transistors in fully complementary CMOS logic. [ 3 ] XOR has the worst-case Karnaugh map —if implemented from simple gates, it requires more transistors than any other function.
Frontal view of an OM-4 camera body, without lens attached Top view of an OM-4 camera body, showing controls. The OM-4 used a horizontal cloth focal plane shutter with a manual speed range of one second - 1/2000 second (up to 240 seconds was possible in automatic mode), plus bulb and flash X-sync of 1/60 second. Unlike most SLRs of the era, the ...
