Default noise source question
wrote:
Hello,

I'm willing to make a noise source from an UHF transistor (B-E
junction reverse polarized like a zener) and I was wondering if it's
ok to use the output attenuator as part of the resistor network for
the DC bias of the transistor (or zener). I'd probably look at the
arrl handbook if I had it ;-)
Thanks

I would think that your biasing of the resistor network would create
some amount of noise which of course would not be attenuated to the same
extent as the semiconductor. But then again it may be negligeable.

Why not build it and try it out?
