Abstract
The GRHN-2.0 is a physical, buildable Real-Time Multi-Domain Harmonic Balancer. It actively monitors the frequency spectra of acoustic, thermal, EM, and vibrational signals, identifying and canceling "harmonic drift" (unwanted resonances and inter-modulation distortion) before they destabilize the system.
In engineering terms, "Gradient Harmonic Balancing" is implemented as a Multi-Channel Active Harmonic Filter (AHF) running on an FPGA. It uses Fast Fourier Transform (FFT) analysis to detect specific harmonic frequencies causing instability and drives actuators (speakers, EM coils, TECs) to inject equal-and-opposite "anti-harmonics," maintaining a state of Harmonic Equilibrium across all physical domains.
This document provides the exact specifications, Bill of Materials (BOM), schematics, and FPGA control logic to construct a prototype that achieves >40dB harmonic suppression and maintains <1% Total Harmonic Distortion (THD) in complex multi-physics environments.
