Processing method for providing, starting from signals acquired by a set of sensors, an aggregate signal and data acquisition system using such method

摘要

Embodiment for forming an aggregate signal from a plurality of starting signals, comprising:
acquiring said starting signals through respective sensors of a homogeneous sensors group;converting acquired signals in respective digital signals having data represented with a predetermined bits number;processing the digital signals to form aggregate signal.;The processing step comprises the operations of:
modifying digital signals changing the data format of each such digital signals from a first format to a second format, each data in the second format having been obtained from a respective data in the first format through an operation of permuting the bits position according to a permutation scheme associated with said data and to the specific digital signal comprising that data;forming aggregate signal obtaining said aggregate signal data by means of a bitwise logic operator acting upon said modified digital signal respective data.

1. An encoder, comprising:
a first node configured to receive a first digital word that includes symbols in respective symbol positions within the first word, the symbols arranged in a first order; a second node configured to receive a second digital word that includes symbols in respective symbol positions within the second word, the symbols arranged in the first order; an aggregator circuit coupled to the first and second nodes and configured to generate an aggregate word by logically combining each symbol within the first word with a symbol in a respective position within the second word with respect to the first order; and wherein the aggregator circuit is configured to change for each symbol within the first word the respective position within the second word in response to a signal from a source remote from the circuit and the first and second sensors.
