System for adaptive signal processing and noise reduction in electronic multi-channel processing systems

Abstract

An adaptive signal conditioning and noise reduction system in a multi-channel electronics processing environment, comprising: a plurality of input terminals configured to receive electrical signals from corresponding channels; a programmable analog conditioning circuit connected to each of the plurality of input terminals, each programmable analog conditioning circuit comprising a variable-gain amplifier, a tunable filter network, and an impedance matching arrangement; a multi-channel analog-to-digital converter circuit configured to simultaneously digitize conditioned signals from the programmable analog conditioning circuits;a digital signal processing circuit electrically coupled to the multi-channel analog-to-digital conversion circuit, wherein the digital signal processing circuit comprises a plurality of parallel processing paths, each having a reconfigurable filter structure and coefficient memory; a cross-channel interaction circuit configured to compute cross-channel correlation parameters and generate compensation signals based on the computed cross-channel correlation parameters; an adaptive control circuit operationally coupled to the programmable analog conditioning circuits and the digital signal processing circuit, wherein the adaptive control circuit is configured to generate control signals for dynamically adjusting gain, filter bandwidth, and filter coefficients based on evaluated signal quality parameters;a memory circuit configured to store historical signal data and adjustment parameters; a time synchronization circuit configured to ensure phase-in-phase operation across multiple channels; and an output interface circuit configured to transmit conditioned and noise-suppressed signals to an external device.
