Title: The Innovations of Jean-Michel Guillaud
Introduction
Jean-Michel Guillaud is a notable inventor based in Montgeron, France. He has made significant contributions to the field of digital transmission systems. With a total of 3 patents to his name, Guillaud's work has had a considerable impact on technology.
Latest Patents
One of his latest patents is a digital transmission system that includes decision means for changing synchronization circuits. This system features synchronizing circuits designed to estimate and compensate for errors between a local oscillator signal and an input signal. The synchronizing circuits consist of a phase/frequency detector and a correction circuit that addresses errors in both unlocked and locked modes. Requests for changing the synchronization circuits from locked to unlocked mode are managed by state control circuits, which only act after specific decision conditions are met. Additionally, these circuits can save and restore adjustments based on the decision condition.
Another significant patent is a receiver with two synchronization loops. This digital transmission system is designed for digitally modulated signals and includes a receiving device that features a demodulator, processing apparatus, and carrier synchronizing apparatus. The synchronizing apparatus is equipped with a first loop for phase/frequency correction and a second loop for phase correction. The operation of these loops is controlled by a mode detector, which determines whether the receiving device is in the process of unlocking or locking. The second loop transforms a phase error signal into a phase correction signal, which is then mixed with the signal from the demodulator.
