Definition: ratio of the power delivered to the load impedance before insertion of the filter to the power delivered to the load impedance after insertion of the filter

Note 1 to entry: The insertion attenuation is generally expressed in decibels.

Note 2 to entry: An example of the frequency responses of a filter is shown in Figure 11. In this figure, various insertion attenuation levels are shown.
