Latest Patents

Robert Hansen's latest patents include a "Digital Automatic Gain Control Method and Device" and a "Method and Apparatus for Numerically Controlled Oscillator."

The **Digital Automatic Gain Control Method and Device** focuses on enhancing the performance of an automatic gain control device. This innovation includes a peak detector that monitors the output of an Analog-to-Digital Converter (ADC), comparing it to previous outputs to determine peak values. Notably, the device features an out-of-range indicator that signals when the ADC input surpasses its dynamic range, allowing for peak value adjustments to maintain signal integrity. Additionally, an error detector works in conjunction with these components to ensure that interference signals are managed effectively while preserving the quality of communication signals.

The **Method and Apparatus for Numerically Controlled Oscillator** describes a sophisticated numerically controlled oscillator (NCO) that incorporates a phase accumulator, phase-to-amplitude converter, and digital-to-analog converter. This system is engineered with both high-speed and low-speed phase accumulation stages, allowing for efficient processing of signals. By partitioning the phase accumulator, Hansen achieves improved performance by utilizing different accumulation periods for distinct parts of the phase word, which optimizes the output while minimizing latency.
