  • Method of synthesis of an analogue noise, noise synthesizer and coding chain using such a synthesiser
    Patent number: 10097194
    Abstract: A method comprises at least the following steps: generating pseudo random noise in the digital domain coded on a number N of bits, sampled at a given frequency FH/N; multiplexing in the digital domain the binary signals produced by each of the N bits at a sampling frequency FH so as to obtain noise coded on one bit at said frequency FH; transferring the noise thus coded into the analog domain via a low-voltage differential transmission interface; filtering the analog signal in a passband which can be centered on half the sampling frequency of an analog-digital converter.
