Embodiment Construction

[0044] figure 2 The described system has four current generators 101 . These current generators are connected in parallel with each other and to a capacitor 102, whereby the current generators are charged by the capacitor. The voltage at the terminals of the capacitor varies according to the law Variety. In this equation, V is the voltage at the terminals of the capacitor in volts, I is the magnitude of the current flowing through the capacitor in amperes, and C is the capacitance of the capacitor in farads. The system also has an activation / deactivation device 103 allowing activation and deactivation of the current generator 101 .

[0045] In this system, the strength into the capacitor depends on the number of current generators connected to the capacitor. Thus, the slope of the increase of the voltage at the terminals of the capacitor depends similarly on the number of this same generator.

[0046] In practice, it is only possible to change the current dynamically to...

Abstract

The system comprises: - a set of at least two electric current generators (101) - at least one capacitor (102) - activation / deactivation means (103) for activating / deactivating said electric current generators (101); the means for generating electric current being connected together in parallel and the capacitor being connected in series with the electric current generators, the activation / deactivation means controlling said generators (101) by means of a digital flow making it possible to control the intensity of the electric current entering said capacitor (102) generating, at the terminals of said capacitor, a trapezoidal voltage signal, said analogue signal being reconstituted by interpolating said trapezoidal signal.

Description

technical field [0001] The invention relates to a system for generating analog signals from various parameters. Without being meant to be limiting, the invention may be used in the fields of telecommunications, radar, sonar, and more generally in all electronic equipment such as medical instruments, test or measurement stands . Background technique [0002] The prior art discloses systems in which the analog signal is predetermined (in this case, the parameters of the signal are fixed) when the system is designed. Systems that generate analog signals on demand (in this case sending parameters to the system in real time) are also known. [0003] In the case of predetermined signals, the following systems are known: [0004] - Systems for generating analog signals using ramp or logarithmic basis functions. By way of example, these basic functions are obtained by using the knee voltage of one or more diodes, [0005] - systems with surface acoustic wave filters (SAW) follo...
