DATA CONVERTER WITH OFFSET TONE REDUCTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18122523 titled 'DATA CONVERTER WITH OFFSET TONE REDUCTION

The present disclosure describes a system with an antenna, a signal generator, data converters, and an aggregator circuit. The antenna provides an input signal to the data converters, while the signal generator generates a random binary sequence received by the data converters. The data converters include an analog circuit and a digital circuit that sample positive and negative polarities of the input signal based on the random binary sequence, reducing an offset tone in the output spectrum produced by the aggregator circuit.

• Antenna provides input signal to data converters
• Signal generator generates random binary sequence
• Data converters sample input signal based on binary sequence
• Analog and digital circuits reduce offset tone in output spectrum
• Aggregator circuit produces final output

Potential Applications: - Wireless communication systems - Signal processing technologies - Radio frequency (RF) devices

Problems Solved: - Reduction of offset tone in output spectrum - Improved signal quality in wireless communication

Benefits: - Enhanced signal processing capabilities - Improved performance of RF devices - Reduction of interference in communication systems

Commercial Applications: - Telecommunications industry - Electronics manufacturing sector - Research and development organizations

Questions about the technology: 1. How does the system improve signal quality in wireless communication? 2. What are the key components of the data converters in this system?

Frequently Updated Research: - Ongoing studies on improving signal processing techniques in wireless communication systems.

Original Abstract Submitted

The present disclosure describes a system with an antenna, a signal generator, data converters, and an aggregator circuit. The antenna is configured to provide an input signal to the data converters. The signal generator is configured to generate a random binary sequence received by the data converters. The data converters include an analog circuit and a digital circuit configured to sample positive and negative polarities of the input signal based on the random binary sequence, reducing an offset tone in an output spectrum produced by the aggregator circuit.
