Title: The Innovations of Georges Martinez
Introduction
Georges Martinez is a notable inventor based in Caen, France. He has made significant contributions to the field of frequency synthesis and digital transmission systems. With a total of 6 patents to his name, his work has had a considerable impact on technology.
Latest Patents
One of his latest patents is a programmable frequency synthesizer designed to have low sensitivity to phase noise. This frequency synthesizer, referred to as SYNT, is intended to supply an output signal with a frequency that depends on the average frequency of an input signal beset with strong phase noise. The synthesizer includes a phase/frequency detector that compares the symbol frequency with a predetermined fraction of the output frequency, supplying a control signal. Additionally, a low-pass filter is used to filter the control signal, while an oscillator provides an output signal with a frequency adjusted by the filtered control signal. Reference pulses with the symbol frequency are generated within the synthesizer using pulses from an internal clock, validated by active states of the input signal.
Another significant patent by Martinez involves a digital transmission system that comprises decision means for changing synchronization circuits. This system includes synchronizing circuits that estimate and compensate for errors between a local oscillator signal and an input signal. The synchronizing circuits feature a phase/frequency detector and a correction circuit for addressing errors in both unlocked and locked modes. Requests for changing the synchronization circuits from locked to unlocked mode are implemented by state control circuits, which only act after applying at least one decision condition.
