A 128-channel digital autocorrelator spectrometer using four 32 channel low power CMOS correlator chips has been built and tested. The CMOS correlator chip uses a 2-bit multiplication algorithm and a full-custom CMOS VLSI design to achieve low DC power consumption. The digital autocorrelator spectrometer has a 20 MHz band width, and the total DC power requirement is 6 Watts.

Results of evaluating the leading order α s corrections to the correlator of tensor currents in pure gluodynamics are presented. These corrections to the parton result for the correlator are not large numerically that allows one to use perturbation theory for the analysis of the resonance spectrum within the sum rules method.

In this paper, we investigate conventional communication-based chaotic waveforms in the context of wireless power transfer (WPT). Particularly, present a differential chaos shift keying (DCSK)-based WPT architecture, that employs an analog correlator at receiver, order to boost energy harvesting (EH) performance. We take into account nonlinearities EH process and derive closed-form analytical e...

Various light-quark channel current-current correlators are subjected to the concept of a non-perturbative component of coarse graining in operator product expansions introduced in a parallel work. This procedure allows for low-energy structure of the OPE-derived spectral function. With naive vacuum saturation for 4 quark operators and using lattice data for the gauge invariant scalar quark cor...

In the framework of the Schwinger-Dyson equation and the Bethe-Salpeter equation in the improved ladder approximation, we calculate the S parameter and an analogue of the π+ − π0 mass difference ∆mπ ≡ mπ+ − mπ0 as well as the NG boson decay constant fπ on the same footing in the large Nf QCD, through the difference between the vector current correlator ΠV V and the axial-vector current correlat...

Abstract We describe the design, validation, and commissioning of a new correlator termed ‘MWAX’ for Murchison Widefield Array (MWA) low-frequency radio telescope. MWAX replaces an earlier generation MWA correlator, extending correlation capabilities providing greater flexibility, scalability, maintainability. is designed to exploit current future Phase II/III upgrades infrastructure, most nota...
