WebI show you how to fix a mis-crossed cable using duplicate stitch. WebThe correct way to consider impedance matching in transmission lines is to look at the load end of the interconnect and work backwards to the source. The reason for this approach is due to the behavior of real electrical signals on a transmission line. All signals that travel on a transmission line are waves, whether they are harmonic analog ...
