Abstract
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, comprises 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 one, of second messages having a second number of bits smaller than the first one; a digital-to-digital converter of the second digital signal into a third one corresponding to a succession, at the second frequency, of third messages having the first number of bits; an interpolation unit providing a fourth digital signal corresponding to a succession, at the second frequency, of fourth messages having the first number of bits; an adder providing the sum of the third and fourth digital signals; and an output digital-to-analog converter.
