An explanatory discussion on applicability follows in Section 3 in terms of the type of transmission (narrowband or wideband) and frequency variation
of the medium, along with an evaluative outline of the comparative novel assets of this travelling-wave approach and the resulting exploitation prospects.
The frequency variation
obtained with the two proposed approaches has been studied.
The rotation speed of the asynchronous motors at the present time is most often controlled by frequency variation
. In this way a very wide speed regulation range, high uniformity of the regulation under changing loads, high speed stability, high efficiency of the electric drive operation and also the reversibility of the speed regulation in respect of the indicated speed are obtained.
Using mixed-signal analog circuitry, it is compensated for frequency variation
due to operating temperature range, initial frequency accuracy, supply voltage change and output load change.
Loose coupling to the load allows some immunity against frequency variation
with changes in load impedance.
Typical frequency variation
is usually [+ or -] 10% from nominal.
A direct assessment of the role of genetic drift in determining allele frequency variation
in populations of Euphydryas editha.
The FM sensitivity of the receiver is important from the point of view of measuring the fine-grain frequency variation
in the intrapulse characteristic.
In addition, to assess the variation in the operating frequency when the diode is ON, we analyzed the frequency variation
according to [L.sub.5], and the corresponding results are listed in Table 2.
With a better sensitivity, a sensor has a larger resonant frequency variation
for a given IOP variation.
Therefore, the experiment for the temperature effect on the sensor was limited to the consideration of the natural frequency variation
of the sensor.
