Title: The Innovations of Alain Albarello
Introduction
Alain Albarello is a notable inventor based in Paris, France. He has made significant contributions to the field of frequency synthesis and speech signal processing. With a total of 3 patents to his name, Albarello's work showcases his expertise and innovative spirit.
Latest Patents
One of Albarello's latest patents is a fractional-division frequency synthesizer for digital angle-modulation. This synthesizer is designed to deliver an angle-modulated output signal based on digital information. It operates by providing an output frequency F.sub.S = (N+k)F.sub.R, where N represents the integral part of a number N+k and F.sub.R is a reference frequency. The synthesizer includes a variable oscillator and an oscillator control loop, which consists of a variable divider, a phase comparator, and a summing device. Additionally, it features a phase accumulator that performs modulo-M summation of a number G=k(M) at the frequency F.sub.R.
Another significant patent involves a process for detecting the melody frequency in a speech signal. This process utilizes a set of data characteristics of the speech signal, which are supplied by processing circuits. It measures the time intervals between zero crossovers and the energy in the half-waves of the signal. A microprocessor implements a test procedure that selects half-waves whose energies exceed predetermined thresholds, minimizing detection errors through complementary tests.
