Default Analyzing Stub Matching with Reflection Coefficients

It is interesting to look at a single short pulse propagating along the
TL. At the stub point, the pulse must encounter a discontinuity in
impedance and therefore there will be a reflection. This can been seen
on a TDR. So there is a real reflection from a stub regardless of
whether or not it is a virtual short.

I thank you for that, Alan, because, to continue, when the pulse is replaced with a sine wave, there is also a
reflection from the stub.


Hi Walt -

Begging your pardon, but don't TDR's examine the transient response of
a system, rather the steady state response?
