In news:

The sampling intermediate-frequency (IF) filter is a high-performance digital device that can bring increased yield to integrated Bluetooth receiver designs.
Emerging electronic sample labeling technologies such as radio frequency identification (RFID), as well as more traditional solutions, are described here.
The sample is loaded into a high-frequency resonant cavity in a slowly varying uniform magnetic field.
The capability of the ADC12Dxx00RF ADCs to sample high input frequencies to 2.7 GHz and higher allows elimination of one or more IF stages in high-frequency receiver designs.

In science:

Following their method, we first compute the transmission versus the sample size at various frequencies with the source and the receiver located at the opposite sides of the sample.

At both frequencies, a sampling time of 0.6 ms was used.
Searches for Giant Pulses from Extragalactic Pulsars
By the law of large numbers and the fact that (Uj , j ≥ 1) is distributed as a uniform i.i.d. sample, it follows that the length of the interval equals the asymptotic frequency of the block of Π(t) containing i, a.s. for every t.

As was mentioned above, sample frequences fℓ are consistent estimators for moments Mℓ (µβ ).

For waveforms that exceed the ATWD capture interval, sampling at a lower frequency is sufficient to capture relevant information at later times.

Table II and Fig. 8 show the frequency with which limit cycles of a given length were found for 10 samples of an N = 800 system at β = 20 using 25 different random starting positions each.

The usual Nyquist Theorem states that for a signal with maximum frequency fmax , one needs to sample the signal at a rate which is at least twice this number.

From the detected fraction of artificial binaries, one can reconstruct the true binary frequency among the artificial sample by statistical means. (For an excellent description of this approach and all related problems, see Kouwenhoven 2006).
