Abstract:
1. A mixer receiving a first analog signal and a first digital signal, corresponding to a succession, at a first frequency, of first messages each comprising a first number of bits, and providing a second analog signal, comprising an analog-to-digital converter of the first analog signal into a second digital signal, corresponding to a succession, at a second frequency greater than the first frequency, of second messages each comprising a second number of bits smaller than the first number of bits; a digital-to-digital converter of the second digital signal into a third digital signal corresponding to a succession, at the second frequency, of third messages each comprising the first number of bits; an interpolation unit providing, from an interpolation of the first digital signal, a fourth digital signal corresponding to a succession, at the second frequency, of fourth messages each comprising the first number of bits; an adder providing a fifth digital signal equal to the sum of the third and fourth digital signals; and a digital-to-analog converter of the fifth digital signal into said second analog signal.
