Tunnel Diode

hello all,

Can any one explain me how can one use Tunnel Diode to detect very
small pulses in time (~ nano seconds) ?

How is the negative ressistence property of Tunnel Diode useful to
acheieve this aim ?

regards

Just tell your professor that his questions
are irrelevant because you can't buy tunnel
diodes anymore.

I am going to have to chastise my wife, who dumped my basement
stock of old parts about 20 years ago. There were several tunnel
diodes in there. She also liberated my several boxes (about 6 cu.
ft) of vacuum tubes, dating back to the '20s and up through the
peak of tubes.

But just think of how much freer you have been ever since!

My wife had me donate a lot more vacuum tubes than that. Two boxes
full, each 4'x4'x3', to a radio club back east. No charge. Just sent
them. Everything from tubes I'd liberated from 1944 radar systems
(VR-150, for example) to more modern TV and radio tubes, including
some miniatures. Stuff I'd been collecting since I was about 11 yrs
old. I think they were put to good purpose.

I would have been much happier with such a disposition. Mine were
just dumped. I didn't even know about it for months. BTW, a VR150
is a modern tube, to me.
