Although, the power spectrum efficiency of a non-constant amplitude envelope is always higher than that of a constant envelope modulation.
12.
That is, Duffing's oscillations are of constant amplitude r but have different frequencies d \ theta / dt depending upon the amplitude.
13.
One transducer is used to generate an elastic wave of constant amplitude and varying frequency, whereas the other is used to detect the sample's resonance.
14.
The signal to be amplified is a train of constant amplitude pulses, so the active devices switch rapidly back and forth between a fully conductive and nonconductive state.
15.
If the plot is essentially flat, i . e ., zero slope, then it is reasonable to assume a constant amplitude in the non-linear model.
16.
In addition to the DC bias magnetic field, an AC magnetic field of constant amplitude, with field strength generating ? 0, is also emitted in the bias coil.
17.
The other case, with ? positive, is the defocusing NLS which has dark soliton solutions ( having constant amplitude at infinity, and a local spatial dip in amplitude ).
18.
When an analog signal of constant amplitude across its frequency spectrum suffers attenuation distortion, some frequencies of the received signal arrive being greater in amplitude ( louder ), relative to other frequencies.
19.
The key in reliable power systems is to avoid power disturbances, which are concerned with deviations of the voltage or current from the ideal single-frequency sine wave of constant amplitude and frequency
20.
In some cases, it is useful to consider constant envelope vibration vibration that never settles down to motionlessness, but continues to move at constant amplitude a kind of steady-state condition.
