Patent ID: 8417500

Claim:
A simulation system for simulating an operation of a sensor intended to convert digitized physical parameters into electrical signals, said simulation system comprising: (a) a first simulation assembly; and (b) a second simulation assembly arranged in parallel with the first simulation assembly, wherein each of the first and second simulation assemblies comprises: a generator that generates, by direct digital frequency synthesis, a digital signal taking account of at least the following parameters: a frequency, an amplitude, a phase and an amplitude offset; a digital-analog converter that converts the digital signal generated by said generator into an analog signal; an interpolator that improves signal/noise ratio of an output signal from said generator; and a calculation unit including a multiplication unit that modulates the analog signal received from said converter with a carrier signal to form an electrical signal that simulates the operation of said sensor, and transmits the electrical signal to a user device; and (c) a single generation unit, linked to said multiplication unit of each of the first and second simulation assemblies, which generates the carrier signal, wherein: the generator comprises a phase accumulator which produces frequency modulation of a signal, and the phase accumulator is configured to receive a binary code that corresponds to the frequency of said electrical signal that simulates the operation of said sensor and that fixes a scanning rate of the phase.
