10. Expressing EMI Suppression Filter Effects
EMI Suppression Filter effects are expressed in terms of
the insertion loss measured in the circuit, normally
specified in MIL-STD 220A. As shown in the 50
impedance circuit in the Figure at right, insertion loss is
represented by the logarithmic ratio of the circuit output
voltage with and without a filter in the circuit, which is
multiplied by 20 and expressed in dB.
Therefore, an insertion loss of 20dB indicates an output
voltage ratio (B/C) of 1/10, and an insertion loss of 40dB
indicates an output voltage ratio (B/C) of 1/100.
