An amplitude bound has the added virtue of producing solutions having reduced noise sensitivity, fewer artifacts, superior resolution, and possible bandwidth extrapolation. In contrast, methods having an output that is linear in the irradiance data i(x) either produce artifacts or trade off resolution to suppress artifacts. If a bound makes physical sense and can be computationally afforded, use it. Simple clipping of unphysical parts does not always work well, however. Subtle techniques may be more desirable. [Pg.130]

For the STFT case, the bandwidth of the filter-bank is inversely proportional to the duration of the short-time frame and it is shown in [Cappe and Laroche, 1995], using standard results concerning the simultaneous frequency masking phenomenon, that the processing can suppress audible signal components (ie. components that were not masked by the additive noise) if the short-time duration is well below 40 ms. [Pg.101]

The suppression of superconductivity in (NH3)K3C60 has been attributed to the crystal symmetry lowering that lifts the luorbital degeneracy and decreases the (U/W)c ratio for the transition to the AFM Mott insulating state. This is aided by the increased interfullerene separation (10.57 A) in the ab plane (substantially larger than the value of 10.05 A found in K3C60), which reduces the bandwidth, Wy and increases further (U/W). [Pg.140]

A clue is obtained by careful examination of the crystal structures. It was found that in Ba4C60 there are several considerably small interatomic distances between Ba and C, one of which is 2.990(4) A, almost identical to the sum of the ionic radius of Ba2+ and the van der Waals radius of C. This short interatomic distance is strongly suggestive of strong hybridisation of Ba(5d) and C(2p) orbitals that causes bandwidth broadening [61]. The increase of the bandwidth suppresses several instabilities to the insulating states [71], which are often observed in the tlu compounds. This conjecture is also supported by first-principles calculations... [Pg.153]

The achievable pulse length is determined by the total number of modes that can contribute to the pulse. The broader the frequency comb the shorter the possible pulse length, ideally reaching the so-called Fourier limit. In fact, the spectral width is usually limited by the width over which the GVD and higher order terms can be compensated for by mode pulling [5,6]. Cavity modes that are outside this bandwidth are suppressed without the help of the Kerr-lens effect and do not oscillate. [Pg.127]
