Theoretical and Implementation Aspects of Pulse Streams: an Overview
نویسنده
چکیده
This tutorial paper presents an annotated overview of existing hardware implementations of Artificial Neural Systems based on “Pulse Stream” modulations. Pulse Streams are quasi-periodic binary waveforms which convey analog information on waveform timing. The theoretical bases of Pulse Stream computation are shown for the major techniques, and basic circuits are briefly described for most Neural and Fuzzy functions. Pulse Stream modulations and multiplexing are then analyzed in terms of accuracy, response time, and both power and energy requirements. The performances of the various techniques are compared both with each other, and with those of other analog computing systems.

Ultra-short pulse is a promising technology for achieving ultra-high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We...

متن کاملA New Mathematical Model for the Prediction of Internal Recirculation in Impinging Streams Reactors
A mathematical model for the prediction of internal recirculation of complex impinging stream reactors has been presented. The model constitutes a repetition of a series of ideal plug flow reactors and CSTR reactors with recirculation. The simplicity of the repeating motif allows for the derivation of an algebraic relation of the whole system using the Laplace transform. An impinging stream...
