Title: Innovations of Denis F Cointot
Introduction
Denis F Cointot is a notable inventor based in Paris, France. He has made significant contributions to the field of telecommunications and signal processing, holding a total of four patents. His work focuses on enhancing the efficiency and performance of digital signal processing systems.
Latest Patents
One of his latest patents is the "Binary-to-bipolar converter." This invention converts two binary signals into positive and negative bipolar pulses alternately corresponding to a '1' logic state of the binary signals. The main objective of this invention is to reduce the transient trailing of the rear edges in the bipolar pulses. This is achieved by delaying the transition from low impedance to high output impedance states through control signals or an integrator circuit. The converter also calibrates the rise times of the bipolar pulses, allowing for the use of CMOS circuits upstream.
Another significant patent is the "Device for digit rate reduction of PCM-signals." This system comprises a predictor stage, an automatic gain control stage, and a quantizer stage for adaptive quantizing. The predictor stage includes a subtractor that provides a difference signal representing prediction error to the AGC stage. The quantizer encodes the divided signal into a reduced rate signal, adapting the coding to the statistical properties of the PCM input signal.
Career Highlights
Denis has worked with prominent companies in the telecommunications sector, including Société Anonyme de Télécommunications and SAT (Société Anonyme de Télécommunications). His experience in these organizations has contributed to his expertise in developing innovative solutions for digital signal processing.
