Title: Pierre-Olivier Jouffre: Innovator in Electronic Components
Introduction
Pierre-Olivier Jouffre is a notable inventor based in Grenoble, France. He has made significant contributions to the field of electronic components, particularly in the area of radiofrequency transmission. With a total of 5 patents to his name, Jouffre's work has had a considerable impact on satellite digital telebroadcasting.
Latest Patents
One of Jouffre's latest patents is an electronic component that allows for the decoding of a radiofrequency transmission channel conveying coded digital information. This component is fully integrated onto a monolithic substrate and includes a tuner, a demodulator, and a channel decoder. The overall filtering is executed in two parts: baseband analog filtering and digital Nyquist filtering, which removes information from adjacent channels. The output is a stream of MPEG data.
Another significant patent involves a tuner of the type having zero intermediate frequency, which includes an analog block, a digital block, and an analog/digital conversion stage connected in between. The analog block features a first attenuator/controlled-gain amplifier stage connected upstream to a frequency transposition stage. During initialization, the overall mean power of the entire signal received by the tuner is calculated. This calculated power is then compared in the digital block with a predetermined reference value, allowing for adjustments to minimize deviation. In normal operation, one of the channels of the received signal is selected, with the gain of the first attenuator/amplifier stage being fixed.
