5.2 LC and RC Values Area Judgments [LCRC AREA]
What are LC and RC values?
The equivalence circuit for the impulse tests is viewed as a LCR linear equivalence circuit as shown
in the diagram below, and is the value that was quantified as the 2 parameters of “L * C” value and
“R
*
C” value using the equivalence circuit and impulse response waveform data.

IMPORTANT
The LC and RC values are values approximated from the impulse response waveform. Accurate
equivalence circuit parameter values may be different.
