ANALOG-TO-DIGITAL SPURIOUS NOISE IMPROVEMENT USING A PSEUDO-RANDOM BINARY SEQUENCE GENERATOR

摘要

This invention relates to a noise mitigator (400) for use with an analog-to-digital converter (435) for reducing the spurious noise that is generated as a byproduct of the conversion process. The noise mitigator (400) includes a pseudo random binary sequence generator (410) that provides noise signals at a frequency outside of the frequency range that is providing information. The noise signals are combined with the analog signals before the input to the A/D converter (435), where the combintation of the signals reduces the spurious noise signals.
