Web17. mar 2024 · The power that comes out of the component is called the transmitted power, and it is less than the incident power for two reasons: 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.
