However, during World War 2 John Randall and Harry Boot built on Hull's concept to develop the modern cavity magnetron, the first device which could produce high power at microwave frequencies, and the resulting centimeter-band radar proved a crucial advantage for the Allies in aerial warfare.
Sinusoids are an important type of periodic function, because realistic signals are often modeled as the summation of many sinusoids of different frequencies and different amplitudes (with a Fourier series or transform).
The telescope design incorporates many new features, including hydroformed antenna surfaces, a log-periodic feed covering the entire range of frequencies from 500 MHz to 11.2 GHz, and low-noise, wide-band amplifiers with a flat response over the entire band making it possible to amplify the sky signal directly.

Leyden jars or more powerful devices employing flat glass plates alternating with foil conductors were used exclusively up until about 1900, when the invention of wireless (radio) created a demand for standard capacitors, and the steady move to higher frequencies required capacitors with lower inductance.
Waite was investigating the high number of aircraft crashes in Antarctica when he discovered that certain radar frequencies were not reflected from the surface of the ice, they penetrated through to the land surface below giving false altimeter readings.
Grey noise is random white noise subjected to a psychoacoustic equal loudness curve (such as an inverted A-weighting curve) over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencies.

Through the use of modulators with frequencies that are non-integer multiples of the carrier signal (i.e. non harmonic), atonal and tonal bell-like and percussive sounds can easily be created.
Grey noise is random noise subjected to a psychoacoustic equal loudness curve (such as an inverted A-weighting curve) over a given range of frequencies, giving the listener the perception that it is equally loud at all frequencies.
Observations with high resolution radio telescopes such as VLA, MERLIN and VLBI show a bi-polar outflow of charged particles, which emit synchrotron radiation at radio frequencies.

Other frequencies are 97.1 MHz FM from Chedington (near Crewkerne), which is at 400 watts, but again directional in order to prevent interference with nearby Wessex FM from the Dorchester area, which broadcasts on 97.2 MHz FM.
After an expenditure of about US$250,000 and 2,500 man-hours, Northrop's Ho 229 reproduction was tested at the company's classified radar cross-section (RCS) test range at Tejon, California, where it was placed on a 15-meter (50 ft) articulating pole and exposed to electromagnetic energy sources from various angles, using the same three frequencies in the 20–50 MHz range used by the Chain Home
In 2003, British statistician and evolutionary biologist A. W. F. Edwards faulted Lewontin’s statement for basing his conclusions on simple comparison of genes and rather on a more complex structure of gene frequencies.
Special care must be taken in the design of the scaling filter to ensure that spatial frequencies remain balanced in all areas of the image, and that the Nyquist criterion is met in all areas of the image.
The task of frequency planning in GSM mobile networks involves distributing available frequencies across the antennas so that users can be served and interference is minimized between the antennas.
However, on November 24, 2010, after the FAA "had previously imposed a condition on the tower owner to coordinate any new frequencies on the tower," Connoisseur cancelled its CP and the FCC deleted the 107.7 FM frequency.

But testing is not confined to DC (zero frequency); often an operational amplifier will also have its PSRR given at various frequencies (in which case the ratio is one of RMS amplitudes of sinewaves present at a power supply compared with the output, with gain taken into account).
While acknowledging Lewontin's observation that humans are genetically homogeneous, A. W. F. Edwards in his 2003 paper "Human Genetic Diversity: Lewontin's Fallacy" argued that information distinguishing populations from each other is hidden in the correlation structure of allele frequencies, making it possible to classify individuals using mathematical techniques.
It broadcasts on 89 MHz in Greater Helsinki area, and on other frequencies in most other big cities in Finland.

However, Yugoslav Secretary of Defense and JNA chief of staff, general Veljko Kadijević reneged on the earlier promise, saying that JNA needs its frequencies for flight path control and doesn't have sufficient funds in its budget to service a television network thereby effectively killing Yutel's plans of broadcasting independently of the local constituent republic TV centers.
