Title
(EN) Signal reception multi-tuner system and corresponding method
Abstract
(EN)

A Multi-tuner reception system includes at least a first tuner and a second tuner. The first tuner is adapted to translate a frequency of a first received signal into a first translated frequency. The first tuner includes a first local oscillator operating at a first local oscillator frequency. The second tuner is adapted to translate a frequency of a second received signal into a second translated frequency. The second tuner includes a second local oscillator operating at a second local oscillator frequency. The second local oscillator frequency is equal to a sum of the first local oscillator frequency and a continually time variable offset frequency.
