Introduction

Philippe Salembier is a notable inventor based in Paris, France. He has made significant contributions to the field of signal processing, particularly in the context of television systems and frequency modulation. With a total of 3 patents, his work has had a considerable impact on the technology used in modern communication systems.

Latest Patents

Salembier's latest patents include an apparatus that features an improved device for recovering the d.c. component. This apparatus performs a processing operation on signals in a transmission system, which conveys analog luminance and chrominance information components associated with periods of the coded digital signal. For instance, a receiver in a MAC television system exemplifies such a device. The device for recovering the d.c. component includes an encoding member that realizes an encoding operation from the decoded digital signal. It also features an estimation circuit that calculates the d.c. component correction signal and a subtraction circuit that subtracts this correction signal from the received digital signal throughout the duration of a line. Additionally, the apparatus includes a filter that utilizes d.c. component correction signals from several line scanning periods to enhance the correction signal.

Another significant patent is for an apparatus designed for decoding coded frequency modulated signals. This circuit eliminates the perturbing effects of noise pulse signals by coupling the signal to be detected through a filter. The filter's transfer function is related to the conjugated transfer function of the frequency modulation deemphasis filter. A comparison circuit provides the output signal when it exceeds a threshold level, while a decision circuit generates noise correction pulses to eliminate the effects of noise.
