Sentence examples for power items from inspiring English sources

Eyeglasses, which sharpened vision, became power items.

Thus, it can be seen that the modulated signal has been contaminated around the carrier frequency by the third and larger odd power items.

From Eq. (28) and Fig. 3, it is not difficult to find out that even power items produce even order harmonic frequency band up to the specific even order, and odd power items produce odd order harmonic frequency band up to the specific odd order.

If a nonlinear section has the odd symmetry property, namely f(−x) = − f(x), then all the even power items at the right side of equation (9) will disappear.

The spectrum attenuated at the band edge, so magnitude 0.1 is taken to calculate the bandwidth ratio of the first 10 power items to the baseband signal, the result is indicated in Table 1.

Compared to the bandwidth of the baseband, the bandwidth of frequency band generated by the high power items of the baseband signal that has passed through nonlinear section of a digital radar receiver is wider.

Spectrum of the first power to the fifth power item is shown in Fig. 3.

Fig. 3 Spectrum of the first power to the fifth power item.

In theory, the bandwidth generated by nth power item is n times of the width for the baseband.

From this, the spectrum of the nth power item can be deduced: {X}^{otimes n}(f)={displaystyle sum_{m=0}^n{C}_n^m{X}_b^{otimes n}left[f+left n-2mright)Fright]}.

If you came across one of these sculptures in a cave or in the basement of a dusty antique shop, you'd have the fleeting sense that you've discovered an alien artifact, some sort of supernatural power item that will either bestow special powers upon you, or suck you and everything around you into oblivion like the portable black hole from The Arrival.
