Latest Patents

One of Serge Surie's latest patents is an automatic equalizer for digital transmission. This invention includes an automatic gain control circuit designed to maintain a constant peak amplitude of the equalized signal. It features a variable equalization network with a control input that allows for modifications to the slope of its gain transfer characteristic without affecting the gain value at the half Baud frequency. Additionally, it incorporates a servo-control system that manages the frequency spectrum shaping by controlling the variable equalization network. This system includes a circuit for detecting the mean phase error of zero crossings in the skirts of pulses in the received and equalized digital transmission signal.

Another significant patent is a frame synchronization device. This device utilizes a frame alignment word decoder connected to the outputs of a shift register that receives the data bit stream. It is clocked by a clock signal generated from selected periods of the data bit stream timing signal, which reproduces a periodic pattern. This pattern is formed by relative bit locations within the duration of a frame, with certain bits distributed according to the alignment word in a frame. The clock signal is generated by a divider that divides by 20 or 21, imposing a periodic phase skip until the alignment word is recognized by the decoder.
