Title: Anker Bjorn-Josefsen: Innovator in Digital Audio Systems
Introduction
Anker Bjorn-Josefsen is a notable inventor based in Lynge, Denmark. He has made significant contributions to the field of digital audio systems, particularly in the area of volume control mechanisms. His innovative approach combines both analog and digital technologies to enhance audio performance.
Latest Patents
Anker holds a patent for "Digital compensation of analog volume control gain in a digital audio amplifier." This invention discloses a digital audio system that integrates analog and digital volume control. The system utilizes a variable power supply voltage to bias a power amplifier for each channel, applying a bias voltage that corresponds to an analog volume control signal. The digital gain control circuitry compares this bias voltage with the expected level for the analog volume control signal. If the bias voltage does not decrease in response to a reduction in the analog volume control signal, the digital gain control circuitry reduces the digital gain of the input digital audio signal until the bias voltage reflects the reduced volume. Additionally, the invention includes methods for modeling the audio system to derive a digital gain control signal based on the desired volume and the amplitude of the digital audio signal.
