Tham -
I would be interested in hearing about the application myself. This is the
opposite of what one would think. On x-mission lines inductance produces
ringing (underdamped), decreases capacitance, and modulates Zo (H(w)the
propagation function is frequency dependent) producing phase delays that
increase both conversion of differential-to-common mode noise, and jitter.

Subject: [SI-LIST] : inductor

SI Gurus,

I have told by an EMI engineer about using inductors can reduce ringing of
a transmission line effectively instead of series resistor. Can anyone
tell if this is true?
As far as I know, inductor can act as a filter to cut unwanted harmonnics.
How do we chose the suitable value for the inductor?

Thanks.

Regards,
KTTHAM
