This test can be done on the unit consisting of the high-frequency pulse generator simulating the noise signal within the actual frequency range, and of the receiving unit, such as oscilloscope, spectral analyzer or electronic voltmeter with the extended frequency range.
For all pickness pe capacitance C'(+) changes very slowly in pe whole frequency range whereas for pe pickness 0.32mm and 0.42mm pere is a kink in pe C'(+) 10 Hz which is a dipolar response.
Figure 4 reports the viscoelastic spectra of the studied rubbers over a wide frequency range (up to 1,500 Hz).
Since a WT maximum in this frequency range occurs for many depths and all three filter ranges, this frequency may be useful for the determination of arrival times.
The cross over frequency is 8 GHz and the units utilize dual oscillator circuits with a switch to provide the full frequency range. Band select is accomplished with a simple TTL signal.
* CSM3500 -- a man-portable ESM/DF system with 30-MHz instantaneous bandwidth, covering the frequency range of 2 MHz to 3.5 GHz.
The scrambling algorithm ensures that even when a long string of the same 8-bit data value is sent, such as a long string of hex 00's, the transmitted data will be constantly changing, thus spreading the emissions over a wider frequency range.
The value of a standard capacitor may vary slightly with frequency because the imperfect medium between its electrodes has varying degrees of dielectric relaxation over the frequency range and the leads and electrodes of the capacitor have residual inductance.
On the other hand, FTIR covers a broader frequency range of 2500 to 10,000 nm or more, hence it gathers a richer amount of spectral information.
Frequency stability down to ffl5ppm is possible with the X21 crystals and other specifications include frequency range from 20 to 54MHz fundamental mode, shunt capacitance of 2 to 4pF typical and drive level of 10[micro]W typical, 100[micro]W maximum.
Plans to sell a 3G licence in the CDMA standard, using a 450MHz frequency range, were unveiled by Moldova's government last week.
This system operates in a 1525 to 1559 MHz receive frequency range and a 1626.5 to 1660.5 MHz transmit frequency range.
