Low Power Analog Correlator for Spread Spectrum Time Domain Reflectometry

Analog correlation is an important analog signal processing function. A new analog correlator circuit for implementing Spread Spectrum Time Domain Reflectometry (SSTDR) technique is proposed. SSTDR technique, makes locating intermittent faults possible, by continuously testing live wiring networks. The proposed correlator circuit is more linear by almost an order of magnitude and consumes half ...

Multiphoton Ionization of Uracil at 355 nm

We present the experimental results from ionization and dissociation by multiphoton absorption (MPI) of uracil and a mixture of uracil with Ar using a Reflectron time of flight spectrometer along with radiation from 355 nm at pulsed Nd:YAG laser . We focus on the light ions production. The MPI mass spectra show that the presence and intensity of the resulting ions depend on the density power of...

Low Power Parallel Spread-Spectrum Correlator

David Garrett and Mircea Stan [email protected], [email protected] University of Virginia, Department of Electrical Engineering AbstractDirect Sequence Spread Spectrum (DSSS) transmissions require a despreading stage within the standard receiver block to recover the spread spectrum signal. For long spread spectrum codes, the correlation block can be a large portion of the receiver size, he...

All optical three dimensional spatio-temporal correlator for automatic event recognition using a multiphoton atomic system

We describe an automatic event recognition (AER) system based on a three-dimensional spatio-temporal correlator (STC) that combines the techniques of holographic correlation and photon echo based temporal pattern recognition. The STC is shift invariant in space and time. It can be used to recognize rapidly an event (e.g., a short video clip) that may be present in a large video file, and determ...

A correlator of time intervals between pulses.

I n the field of neurophysiology, analysis of the majority of neuronal data has been a tiresome task. Many questions and hypotheses posed by investigators in the field have remained unanswered and / or unverified because of inadequate analytical tools. For example, in the course of research at APL by F. F. Hiltz*, the need arose for an inexpensive means of ascertaining time relationships betwee...
