    摘要： A circuit board includes multiple signal layers, in which signal lines are routed, and reference plane layers, in which power reference planes are provided. To connect signal lines at different signal layers, vias are passed through at least one signal layer and at least one reference plane layer. At the one signal layer, a first clearance (or anti-pad) is defined around the via. At the reference plane layer, a second clearance is defined around the via. The second clearance is larger in size than the first clearance to match the impedance of the via as closely as possible with the impedance of a signal line the via is electrically connected to.

    摘要： A printed circuit board includes multiple layers on which electrically conductive traces reside, where at least two of the electrically conductive traces each has a first portion formed on one layer of the printed circuit board and a second portion formed on another layer of the printed circuit board. The printed circuit board also includes a thru-hole via that includes at least two electrically conductive portions electrically isolated from each other, such that each of the electrically conductive portions connects electrically to both the first and second portions of a corresponding one of the electrically conductive traces.

    摘要： A test mechanism includes test equipment to measure frequency-domain data, such as scattering or S parameters. The S parameters are transformed to a different type of network parameters, such as transmission or T parameters. Contributions of test fixtures can be easily removed for the overall T-parameter matrix of a device under test connected in cascade with the test fixture. The test mechanism provides accurate measurement of a device under test represented by a multi-port (greater than two ports) network that is cascaded with another multi-port network representing the test fixture.

    摘要： A transmission for a motor vehicle, including an input shaft a countershaft parallel the input shaft, an output shaft arranged coaxial with the input shaft and a plurality of speed ratio gearwheel pairs. One gearwheel of each speed ratio gearwheel pair is carried on the countershaft and the other gearwheel carried on either the input shaft or output shaft. Each speed ratio pair comprises a fixed gearwheel and a loose gearwheel. A constant ratio is arranged between the countershaft either the input shaft or output shaft for transmitting a selected speed ratio from the input shaft to the output shaft. An input synchronizer releasably connects and releases the input shaft and the countershaft.
