discrete spectrum

A pattern of data distribution that consists of a series of isolated spikes or clusters of data, which are often integer multiples of a fundamental frequency (harmonic), rather than a continuum of data.

The new eLTE-DSA solution overcomes the challenge of insufficient continuous dedicated spectrum resources around the world by using 4.5G technology to aggregate traditional VHF/UHF narrowband discrete spectrum into broadband spectrum resources.
On the other hand, in the case of the potentials with nonempty discrete spectrum and/or semibound states (the latter appear if the Jost function has zeroes at the end points of the continuous spectrum; see [12]), some modified forms of (60), (61) should also exist.
If the discrete spectrum of the IG is present in the current and voltage curves, conditions (1) and (2) take the following form:
Center a Discrete Spectrum. As initially explained in Section 2.3, the spectrum of a continuous function s(t) is defined in the range of -[infinity] < [omega] < [infinity].

Under computation, we have taken into account from 100 to 200 modes of the discrete spectrum (3) and from 10000 to 20000 modes of the continuous spectrum (5) on the grid of the integration argument [beta] of the step [DELTA][beta] = 0.1.
