  • Frequency
  • Here, we show that forskolin, a tool that increases [cAMP] in , affects the magnitude and frequency spectrum of the continuous and discrete components of dark noise in photoreceptors. (pubmedcentralcanada.ca)
  • https://aja.pubs.asha.org/article.aspx?articleid=2109134 Modeling the Influence of Acoustic Coupling of Hearing Aids on FM Signal-to-Noise Ratio Purpose A model was developed to examine variables that influence signal-to-noise ratio (SNR) at the tympanic membrane (TM) when using a hearing aid (HA) and frequency modulated (FM) system.

  • Purpose A model was developed to examine variables that influence signal-to-noise ratio (SNR) at the tympanic membrane (TM) when using a hearing aid (HA) and frequency modulated (FM) system. (asha.org)
  • The primary difference in SNR is in the low frequencies and depends on the amount of low frequency insertion gain and the noise levels at the HA and FM microphones. (asha.org)
  • Adding the reversed spectrum to the observed spectrum is equivalent to zeroing the imaginary channel since the FT of a real signal (with no imaginary signal) always gives a spectrum symmetric about the carrier frequency. (blogspot.com)
  • To determine whether stream noise can act as a cue regarding the microhabitat characteristics of senders, we performed phonotaxis experiments using stimulus pairs constructed with synthetic male calls (high or low dominant frequency) and stream noise with varied signal-to-noise ratios.

  • Gaussian
  • In order to demonstrate the central importance of S/N versus signal alone we have created a simple software that simulates random chromatographic noise and peaks which are Gaussian envelopes with random number of ions per mass spectrum for a given number of total ions in that peak.

  • estimates
  • We show that the SNR estimates a ratio of expected prediction errors. (pnas.org)
  • We show that the SNR estimates a ratio of expected prediction errors and extend the standard definition to one appropriate for single neurons by representing neural spiking activity using point process generalized linear models (PP-GLM). (pnas.org)
  • stimulus
  • In analyses of four neural systems, we show that single neuron SNRs range from −29 dB to −3 dB and that spiking history is often a more informative predictor of spiking propensity than the signal or stimulus activating the neuron. (pnas.org)

  • In order to provide a reliable power control, the base station sends which known signals that are used by these performance indicators to the mobi len participants. (google.com)
  • baseline
  • However, while the noise level (baseline) increases linearly with the number of ions the noise fluctuation which is the noise in S/N, increases only as the square root of the number of baseline ions. (avivanalytical.com)
  • fluctuations
  • Continuous noise is produced by spontaneous fluctuations of the catalytic activity of the cGMP phosphodiesterase. (pubmedcentralcanada.ca)
  • The "continuous" noise is plausibly attributed to spontaneous fluctuations of the catalytic activity of the cGMP phosphodiesterase ( Rieke and Baylor, 1996 ). (pubmedcentralcanada.ca)
  • experimental
  • Taguchi primarily recommends experimental design as a tool to make products more robust- to make them less sensitive to noise factors. (scribd.com)
  • However, this benefit was counterbalanced by the slow and unstable time-dependent response at high SWNT concentrations, arising from reduced Schottky barrier heights between the active layer and electrodes.At high SWNT concentration, the dark current also increased due to the reduced Schottky barrier height, leading to decrease the signal-to-noise ratio (SNR) of the device.Experimental results indicated that 0.005 wt.

  • The difference in the signal-to-noise-ratios for the two samples in the thick-walled NMR tube may very well be the same within experimental error as the signal-to-noise-ratio is very sensitive to magnet shimming. (blogspot.com)
  • If the signal-to-noise ratio for the 0.45 mL sample is multiplied by (0.68 mL/0.45 mL), the corrected value is 557 which is very likely the same as the 566 value measured for the 0.68 mL sample in the thin-walled NMR tube within experimental error. (blogspot.com)
  • found
  • I have found that the signal related to the FID of the imaginary channel does not happen at the same time as the real channel and that causes the spectrum to be asymmetric. (blogspot.com)
  • real
  • The discrete noise is generated by spontaneous thermal activations of the visual pigment, which evoke waves of photocurrent indistinguishable from responses of the cell to real photons. (pubmedcentralcanada.ca)
  • Although signals contain non-random intelligence and can be isolated and separated, with a 0 SNR, it is more difficult to isolate the signal in real time and might be better handled in a batch process offline. (thefreedictionary.com)
  • depends
  • It is important to remember that the quality of the signal depends on both biological and technical factors (based mainly upon the design considerations used in the array scanner). (moleculardevices.com)
  • characteristics
  • The camera was the first and is the only in the industry to offer 95 percent QE by leveraging BSI technology, combined with large pixels and low-noise characteristics to maximize light collection. (photometrics.com)
  • data
  • As an example for low signal-to-noise ratio (SNR) microscopic image sequences we have applied this method to noisy in vitro motility assay data, where fluorescently labeled actin filaments move over a surface of immobilized myosin. (spiedigitallibrary.org)
  • From the data, one sees a 35-40% loss in signal on going from a thin-walled to a thick-walled NMR tube. (blogspot.com)
  • communication
  • Many kinds of environmental noise can interfere with acoustic communication and efficient decision making in terrestrial species. (springer.com)
  • Thus
  • Stream noise associates closely with rocks, topographies and vegetation and may thus provide useful microhabitat information for signal receivers, thereby acting on sexual selection. (springer.com)
  • amount
  • The amount of NMR signal is expected to be proportional to the amount of sample inside the coil of the NMR probe. (blogspot.com)
