First of all, my apologies. As you can gather it is the first time I post in
this newsgroup. In the process, the computer kept on telling me that I
required authentification (I had forgotten to click on one of the boxes) and
said that it could not send the message. I therefore ended up writting it
several times. As it turned out, two of the times where it told me it had
not sent it, it had. I greatly apologise for all the inconvenience.

Secondly, yes, I mean to say the signal has a DC component. I would have
thought that impulsive noise, being cause by electron movement would produce
an AC signal, otherwise where does the DC come from? The importance of the
time is because I would have thought that in the long term the antenna would
resonate so as to produce a zero mean signal (AC). Sorry, the answer might
be common sense but I just fail to see it.

Thank you for your time and once again, sorry.

Hello, thank you for reading this post.

When analysing wideband impulse signals from a wideband antenna I have
realised that the average signal magnitude is not zero. I have thought
this
is because the reactance of the antenna at different frequencies varies
and
since it is a wideband antenna there can be energy measured since it is
only
for an extremely small period of time of 2-4 us. However, I am not sure
and
would greatly appreciate the views of this newsgroup.
