This paper proposes a new amplitude and phase demodulation scheme different from the traditional method for AM-FM signals. The traditional amplitude demodulation assumes that the amplitude should be non-negative, and the phase is obtained under the case of non-negative amplitude, which approximates the true amplitude and phase but distorts the true amplitude and phase in some cases. In this pap...

In this paper we continue the theoretical study of the possible applications of the ∆-tree data structure for multiple-valued logics, specifically, to be applied to signed propositional formulas. The ∆-trees allow a compact representation for signed formulas as well as for a number of reduction strategies in order to consider only those occurrences of literals which are relevant for the satisfi...

In this paper, we consider an information-theoretic formulation of the content identification under search complexity constrain. The proposed framework is based on soft fingerprinting, i.e., joint consideration of sign and magnitude of fingerprint coefficients. The fingerprint magnitude is analyzed in the scope of communications with side information that results in channel decomposition, where...

In this paper, we investigate the collapsing of eight multioperand addition related operations into a single and common (3:2)counter array. We consider for this unit multiplication in integer and fractional representations, the Sum of Absolute Differences (SAD) in unsigned, signed magnitude and two’s complement notation. Furthermore, the unit also incorporates a Multiply-Accumulation unit (MAC)...

We develop a perturbative QCD factorization theorem which is compatible with effective field theory. The factorization involves three scales: an infrared cutoff of order ΛQCD, a hard scale of order the B meson mass, and an ultraviolet cutoff of order the W boson mass. Our approach is renormalization group invariant and moderates the scale-dependence problem in effective field theory. Applying t...

The thermomagnetic force for small spheroidal particles is given in the Waldmann limit. In this limit the force is proportional to the surface area of the particle, and depends on the gas pressure p and on the magnetic field strength H only via H/p. For the gases HD, CH 4 , CO and N2 the ratio of the thermomagnetic and thermal forces is calculated from Senftleben-Beenakker effect data. It is po...

We show that the singular sources in the energy-momentum tensor for the RandallSundrum brane world, viewed as a solution of type IIB supergravity, are composed of two elements. One of these is a D3-brane source with tension opposite in sign to the RS tension in five dimensions; the other arises from patching two regions of flat ten-dimensional spacetime. This resolves an apparent discrepancy be...

The authors present a number of complete cores which are specially tailored for the low power implementation of FIR filters executed using block processing. The paper reveals the overall core architecture (and the architecture of its constituent components such as arithmetic unit, controller, and memory) required in order to employ the algorithm such that power is reduced and the overheads are ...

In this paper, we propose an adder which adds two 2’s complement numbers and results a sign-magnitude number. In this way, the conversion from two’s complement number to sign-magnitude number will be merged with addition.
