WebMar 17, 2024 · 1. A portion of the signal gets reflected. 2. The component absorbs a portion of the signal. So, in summary, we express insertion loss in decibels, and it is the ratio of incident power to transmitted power. Furthermore, we can summarize that return loss, which we also express in decibels is the ratio of incident power to reflected power. WebSep 28, 2024 · To introduce the concept of measuring signal integrity in a digital system, we will evaluate a basic measurement of a digital signal taken as if the scope is a part of the system. This means that the output of a digital line is connected directly to a scope through an accessory: Figure 1: Oscilloscope in series with a digital output from a ...
