modulated

Normal laser rangefinders are transmitting the light (modulated), and looking for the reflected return (modulated) at the same location as the transmitter.

Being so broadband means that it's not at all suitable for phase modulated signal because by definition it would have high phase noise.

You could send a message with modulated x-rays, and she might pick them up with a VLF antenna.

A flat tax isn't progressive though (unless modulated by significant exemptions and deductions, and then you're back where you started).

Note that it says the header may be modulated using one method whereas the payload another depending on the header.

This one got mentioned in the discussion of 6 GHz frequency modulated radar [0] here a couple of days ago.

To do this, the seismometer's output signal was greatly amplified, then frequency modulated onto a relatively low frequency carrier (1–2 kHz).

So this would limit ultimately the sensitivity of such an AM modulated system.

So it doesn't have the usual moving parts at all (although it uses modulated laser mirrors instead of a projector for cost reasons).

We were doing this 10 years ago, but we modulated the output to make file downloads look like streaming video.

No, because they send modulated signals over the copper power cables.

Gender roles identities are always modulated by time and place.

:) Like I said, " Like many IR systems, the LEDs and lasers are actually modulated (Alan said, "on the order of MHz").

Consider Ronald Colman, who was a popular actor in the silent film era but whose career didn't take off until the talkies, when the audience fell in love with "his beautifully modulated and cultured voice", or Lars Hanson who believed that his heavy Swedish accent wouldn't do so well in Hollywood so moved back to Sweden.

After a little googling, it looks like the DoD did think of it, it's just not for the like of us: "The Precision (P) code, sometimes called the Precise Positioning Service (PPS), is modulated onto the L1 and L2 carriers allowing for the removal of the first order effects of the ionosphere.
