Sentence examples for frequency narrowband from inspiring English sources

The continuous complex Shannon wavelet transform is adopted to extract the frequency narrowband signals from the frequency wideband impact response signals of the PZT sensors.

The use of spatial frequency narrowband elements allowed for accurate correction of any upstream contrast sensitivity influence and ensured that the orientation bandwidth of our elements did not covary with the measured coherence.

The impact distance relative to the 2D cross-shaped array can be calculated by using the difference of time-of-flight between the frequency narrowband signals of two different central frequencies and the corresponding group velocities.

Based on the designed filter, a wavenumber searching and best match mechanism is proposed to implement the spatial-wavenumber filtering of the frequency narrowband signals without modeling, which can be used to obtain a wavenumber-time image of the impact relative to a linear PZT sensor array.

The RF center measured with the low frequency narrowband sound is referred to as the "low frequency center", and the RF center measured with the high frequency narrowband sound is referred to as the "high frequency center".

Sound bursts consisted of either low (3 5 kHz) or high (7 9 kHz) frequency narrowband noise, 250 ms in duration, with 5 ms rise and fall times.

Interestingly, Syka et al. (2002) reported that gap-detection thresholds in rats were much lower at 70 dB SPL for broadband and low-frequency narrowband noise than when the stimulus level approached an audiometric boundary, where thresholds were as high as 10.6 and 31.3 ms for broadband and low-frequency noise, respectively.

Note that the spatial-channel basis is independent of both time and frequency in narrowband communications.

Due to the small relative signal bandwidth (actual bandwidth divided by the center frequency) of narrowband systems, the Doppler effects can be modeled primarily by frequency shifts[3, 4], in which case it is reasonable to assume that each OFDM subcarrier experiences a statistically identical frequency offset[2 ]

In this work a method for automatic design of narrowband frequency sampling low-pass digital FIR filters is presented.

Frequency compensation in narrowband designs, using L and C matching elements, is not often used or required because the bandwidth is limited to 5% or 10% by the matching element.
