WebThese reflections are caused by impedance mismatches and discontinuities, mainly resulting in ringing within PCB interconnects. Each reflection creates damped oscillations in the signal's transient response, which is associated with the ringing effect. The consequences of signal reflections include signal distortions, overshoots, and undershoots.

In telecommunications, signal reflection occurs when a signal is transmitted along a transmission medium, such as a copper cable or an optical fiber. Some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This happens because imperfections in the cable cause impedance mismatches and non-linear changes in the cable characteristics. These abrupt changes in characteristics cause some of the transmitted si… how many amphibians are there in the worldWeb16 Likes, 0 Comments - OFFICIAL - INFINITY BATAM (@infinity.batam) on Instagram: "Do you miss us?
