Sentences with phrase «signals at higher frequencies»

This allows researchers to record brain signals at higher frequencies and with less interference than measurements from the scalp.

The NIST team is experimenting with low - frequency magnetic radio — very low frequency (VLF) digitally modulated magnetic signals — which can travel farther through building materials, water and soil than conventional electromagnetic communications signals at higher frequencies.

Shepard is part of a team of scientists from Columbia and IBM working under a $ 4 million grant from the Defense Advanced Research Projects Agency (DARPA) to develop field - effect transistors made of graphene, which is particularly good at amplifying weak signals at high frequencies.

Not exact matches

Dolphins can produce sound at frequencies up to 200 kilohertz — around 10 times as high as the highest pitch we can hear — and can also shift a signal's pitch or stretch it out over a long period of time.

But if there are astrophysical events that produce gravitational waves at frequencies too high for LIGO to spot, their memory signals might fall easily into the observatory's detection range, thus allowing us to pick them up.

By looking at the responses of closely related crickets, the scientists found the most likely origin for the female vibrational signal was a startle reflex seen in other crickets in response to loud high frequency sounds.

The upshot was that — just like the signals from natural mechanoreceptors — when more pressure is applied, the oscillators turn out pulses at a higher frequency.

One difference will be that 5G may move wireless signals to a higher frequency band, operating at millimeter - length wavelengths between 30 and 300 gigahertz (GHz) on the radio spectrum.

At low frequencies (< 5 GHz) where pulsar timing are typically performed at, the high - density interstellar medium in the GC can greatly smear out the pulsation signals from the pulsars, which is known as scatterinAt low frequencies (< 5 GHz) where pulsar timing are typically performed at, the high - density interstellar medium in the GC can greatly smear out the pulsation signals from the pulsars, which is known as scatterinat, the high - density interstellar medium in the GC can greatly smear out the pulsation signals from the pulsars, which is known as scattering.

At higher frequencies, the intrinsic strength of the pulsar signals largely decreases as pulsar radio emission usually has a steep spectrum.

«A number of experiments and observations have figured out that, under the right conditions, radio communications signals in the VLF frequency range can in fact affect the properties of the high - energy radiation environment around the Earth,» explained Phil Erickson, assistant director at the MIT Haystack Observatory in Westford, Massachusetts.

Furthermore, New Scientist explained, the signals were detected at a higher frequency than ever before.

Optimal filtering involves removing noise elements that have different frequencies from the signal, and this can be done by setting limits at both high and low frequencies (De Luca et al. 2010).

Similarly, a large amplitude, slow frequency cat - like tail swish means the dog reeeeally doesn't like you and a high frequency, small amplitude vibration at the tip of the dog's perpendicularly held tail, generally signals the animal is extremely tense and stressed and about to react.

Roughly speaking, the frequency spectrum of the noise (El Nino etc) has components at higher frequencies than those of the signal (CO2), so differentiation (finding the trend) worsens the signal to noise ratio.

But would you conclude therefore that low - pass filtering can not improve SNR when the noise is at a much higher frequency than the signal?

High frequencies can not be used to predict low frequencies, something obvious when looking at signals in the Fourier Domain.

It was found for a sinesoidal signal that with 4 samples at the highest signal frequency rate it should be possible to replicate the analog signal.

UHF signals are at a higher frequency, they are more susceptible to being weakened by building materials (walls, plaster, etc.) and are more dependent on a clear line of sight.

Millimeter waves have greater speed capabilities because of their shorter signal wavelengths, broadcasting at much higher frequencies between 30 GHz and 300 GHz — a stark contrast to the current 3G and 4G signals that are broadcast below 6 GHz.

Named the MoVR system, it uses high - frequency radio signals called millimeter waves, pushing out data to the VR headset at speeds in the Gbps range.

Performance Audiophiles might not love what happens to the signal at higher volumes — if a track has deep bass frequencies, like the Knife's «Silent Shout,» digital signal processing is employed to prevent distortion.
