Flat weighting: In a noise-measuring set, a noise weighting based on an amplitude-frequency characteristic that is flat over a frequency range that must be stated.
Note 1: Flat noise power is expressed in dBrn (f1 - f2) or in dBm (f1 - f2). Note 2: "3 kHz flat weighting" and "15 kHz flat weighting" are based on amplitude-frequency characteristics that are flat between 30 Hz and the frequency indicated.
Famous quotes containing the word flat:
“Twenty-two years ago Judge [then-Senator Stephen] Douglas and I first became acquainted. We were both young then; he a trifle younger than I. Even then, we were both ambitious; I, perhaps, quite as much so as he. With me, the race of ambition has been a failure—a flat failure; with him it has been one of splendid success.”
—Abraham Lincoln (1809–1865)
