Abstract: 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.
