The scientists also found that the act of controlling the computer-brain interface led to an increased classification accuracy, which corresponded with improvements in the whole-brain signal-to-noise
A characteristic of all of these curves is that they asymptotically approach 50% errors as the signal-to-noise
ratio becomes very large.
Figures 5b and 7b show that at a relatively short distance of 6 km, the actual signal-to-noise
ratio of the high speed FP laser is, depending on modulation frequency, 10 to 20 dB worse than that predicted from a conventional RIN measurement, which is made without any applied modulation signal.
In spite of the high performance lock-in amplifier used as a second stage signal-amplifier, the signal-to-noise
ratio must be optimized for the output of the photocurrent measuring preamplifier.
For analog televisions, the XC5000 meets an unweighted signal-to-noise
ratio of 54dB and a noise figure better than 6dB.
The program has also developed a novel signal-to-noise
measurement algorithm based on Gaussian mixture estimation procedures.
The resolution and accuracy of the converter is limited by the signal-to-noise
Improvements include a large increase in spatial resolution even at large tip-substrate separation; increase in the signal-to-noise
ratio by more than an order of magnitude; substantial decrease in non-local contributions to the total capacitance; elimination of signal variation from changes in materials contrast and geometry due to wear of the probe tip; and the reduction or elimination of artifacts arising from long-range sampling of substrate topography.
Combining Bluetooth and proprietary noise compensation technologies, sound processing algorithms, techniques that improve signal-to-noise
ratio and other audio science to deliver state-of-the-art personal sound - Sound ID has created a new category of Bluetooth-enabled hearing devices that change the way consumers experience sound.
The perfect crystals provide high angular resolution while the multiple reflections suppress the "wings" of the beam profile, improving the signal-to-noise
ratio to values comparable to that obtained with pinhole instruments.
The SSM2301 and SSM2304 have less than 1 percent total harmonic distortion plus noise (THD+N) when driving peak output loads from a 5 V supply, and a signal-to-noise
ratio (SNR) that is better than 98 dB.
