Title: Innovations by V John Mathews
Introduction
V John Mathews is a prominent inventor based in Salt Lake City, UT. He holds a total of 10 patents, showcasing his significant contributions to the field of audio technology. His work primarily focuses on enhancing audio systems and reducing distortions in loudspeakers.
Latest Patents
One of his latest patents is a digital signal processor designed for audio extensions and the correction of nonlinear distortions in loudspeakers. This innovation involves digital filters that process input audio signals to extend audio capabilities and minimize distortion. The technology allows for modifications to the original frequency response of loudspeakers, enabling targeted sound pressure level extensions. Additionally, a nonlinear digital filter can be applied to the audio signal to reduce distortions, allowing loudspeakers to operate close to their maximum theoretical power without increasing output distortion.
Another notable patent addresses the compensation of air path distortions using a pre-correcting engine. This engine generates a pre-corrected signal to mitigate distortions in sounds produced by loudspeaker systems. By virtually propagating a target signal in reverse, the pre-correcting engine corrects for air path distortions, resulting in high-fidelity sound generation. This approach contrasts with conventional systems that often produce lower fidelity sounds due to air path distortions.
Career Highlights
Throughout his career, V John Mathews has worked with notable organizations, including The Boeing Company and the University of Utah Research Foundation. His experience in these institutions has contributed to his expertise in audio technology and innovation.
