When I say "taken over," I mean that their behavior followed the changes anticipated at very precise frequencies.

Perhaps we should reconfigure the tricorders to this precise frequency.

The gas would release its excess energy as microwaves of a very precise frequency that could be controlled.

Boner reasoned that when feedback happened, it did so at one precise frequency.

The precise frequency of pycnodysostosis has not been determined.

The precise frequency of the tone produced can be quite different depending on the size of the individual instrument.
