Case 1 is obtained for two 250 kHz
transducer in pitch-catch mode without conical reflector, while cases 2 and 3 represent the 250 kHz
transducers with conical reflectors (180[degrees] and 360[degrees] configurations, respectively).
Correlacionou-se os valores de IPRF e LRF as medias dos limiares auditivos tonais dos individuos pesquisados e o IPRF as diferencas de limiares auditivos tonais entre oitavas de frequencias, a fim de verificar como as frequencias de 3 e 4 kHz
influenciam as tarefas de reconhecimento de fala.
The mean hearing levels were lower in the Behcet group than in the controls at all frequencies, but only the differences at 1 kHz
and higher were statistically significant.
channel will remain on the same 25 kHz
The THD percentage was determined for the clipped and restored 1 kHz
sine wave recordings, allowing a detailed measurement of the harmonic distortion of the single discrete signal.
The analysis of variance at 1 kHz
revealed a highly significant difference between groups, F=6.
Results for continuous excitation and 25-45 kHz
filter: VS30-SIC-46dB provides 17 dB more signal amplitude and 9.
Therefore, the problem is apparently impossible to solve, as monetary amounts to be paid or received must be the terms used in KHZ
silicon technology that is competitive with quartz in terms of size, power consumption, and frequency accuracy.
Table III summarizes results collected from measurements of the PMSM motor efficiency for PWM frequencies ranging from 4 kHz
to 20 kHz
with the increment of 1 kHz
, for the speed values of 300 rpm, 500 rpm, 750 rpm, 1000 rpm and 1200 rpm for the constant load torque of 4 Nm.
1a and b for driving pulses of 100 kHz
, 500 kHz
and 900 kHz
The 800 series high-frequency pipe and cable locator is said to be more capable, easier to learn and operate and more rugged It features the same 480 kHz
frequency of the Classic Pipehorn.
Typically, we can hear sounds in the frequency range from 20 Hz to 22 kHz
although the upper end of the range reduces with age.
Customer-specified step sizes range from 10 kHz
to 1 MHz.
NIST staff have recently completed a detailed characterization of the transfer of the farad unit from the Calculable Capacitor to Calibration Laboratory reference standards at a frequency of 1 kHz
