Common mode /Z/ is measured by connecting the filter/choke coil as in Fig. 1. Differential mode /Z/ is measured by connecting the filter/choke coil as in Fig. 2. Differential mode /Z/ is measured by connecting the filter/choke coil as in Fig. 2. Weboperate over the expected frequency band. Note that, unlike the Figure 1 family of RC filters, a choke-only filter offers no differential filtration. Differential mode filtering can be optionally added, with a second stage following the choke, by adding the R1-C3-R2 connections of Figure 1.
