Title: Innovations and Patents of Robert A. Orban
Introduction
Robert A. Orban, an accomplished inventor based in Belmont, California, holds an impressive portfolio of 24 patents. His contributions to the fields of audio processing and modulation have significantly influenced modern technology.
Latest Patents
Among his latest innovations is the patent for "Anti-aliased clipping by band-limited modulation with step functions." This method addresses the computation of 'clippings' in an audio signal within the digital domain to prevent aliasing. The technique involves obtaining an offset signal by subtracting a threshold from the audio samples. These samples are then multiplied by a pulse, which is strategically aligned with the thresholds crossed by the audio signal. The pulse consists of two bandwidth-limited step functions, contributing to its efficiency.
Another notable patent is the "Controller for FM 412 multiplex power regulation." This feedback controller, embedded in FM audio processors, regulates the integrated multiplex power to meet the specifications set by ITU-R 412. It works by applying the square of the multiplex signal to an integrator, removing a constant representing the maximum power threshold. The system involves a sample-and-hold circuit and a second integrator to fine-tune the average power output, enhancing the fidelity of audio transmission through feedback mechanisms.
