White noise is a random signal with a flat (constant) power spectral density.
White noise - signal contains equal power within any frequency band with a fixed width.
(From Wiki.)

That white noise -
snowstorms
with us
This was written some days ago. Trying to "age" it, as a good old wine. Then we got sunny March days.

That white silence -
the snowstorms
left us.
This busy world
around us -

Hello Polona !-)
The snow is a fascinating element, so silent, clean white.
Snow is melting,
some day, some year, sooner or later.
(In Arctic regions it will take sometimes some more times?)
This new snow -
how many times you
have reborn?

"any frequency band with a fixed width" No modulation?
snowstorms -within us-
I really like #1 and #2; stress, and relief. Relief allows us to cope... #3, "this busy world around us."
Yes Magyar, thats pity. No modulation within white noise?
There is a wide radiotransmitter on, but no one keying it.
Sure there is noise built by our own equipments, as actice RF-pre-amplifiers etc.
But if using Dolby-systems it will clean extra "noise" and its silence there? Is it. And what is silence, dB?
(I published a poems collection long time ago named Dolby C. :-)

I learned telegraphy when joined Finnish Navy. Sailed onboard a frigate as one of her radio-oprs.
After that I graduate as an international radio-operator and sailed as a radio-officer (merchant navy, of course) some 20 years. All the time I studied more radio-electronics, and ship's radars which I also maintenanced. I got a certificate for that, too.
Most interesting period was when I was within a training to teach other Radio-officers to understand digital electronics, and then something about computers. etc
When Radio-officers no more needed onboard the ships I joined as a civil to help Finnish Police with those communications and data-systems. Retired two years ago.
I am still working in Finnish Radio Officer's union. I'm a chairman now. Ought to retire therefrom soon, too, I guess.
