Electrical Apparatus Interference Reduction TRIZ Cases

Generates DC voltages from RF signal power while suppressing even and odd harmonics to improve RF circuit operation.

A digital cancellation path uses a DTC and RF digital-to-RF conversion to suppress IMD3 and receiver interference in concurrent transmit operation.

Chassis grounding near a common point shrinks vehicle cable ground loops, attenuates low-frequency EMI, and lowers bit error rates.

Terminal circuitry adjusts functional-module drive voltage or current by communication state, reducing interference linked to dropped calls and blurry screens.

This case synthesizes a motor-interference reference signal from spectral repetition data, reducing noise while preserving desired AM audio.

The case adjusts signal-line voltage or current to balance functional-module immunity with interference in communication modules.

A notch filter selectively removes spectral portions that linearly combine to cause intermodulation interference at narrowband receiver frequencies.

A digital spread spectrum clock generator uses a self-adjusting delay line to modulate system clock frequency.

A tunable decoupling capacitor dynamically adjusts capacitance to filter noise across varying frequencies.

Hermetic sealing and segmentation isolate the health module from interference, preventing regulatory classification as a medical device.

A noise reduction device generates an anti-phase electrical signal to cancel radio frequency interference on isolated power planes.

A network node site controller detects passive intermodulation by correlating uplink and downlink signal statistics.
