A binary modulator and resources for processing the different types of input signals are provided. A programmable digital matrix switch for input signals is used to route the input signals to the resources corresponding to the types of the signals. Alternatively, or additionally, the card includes an output signal modulator and an output signal programmable digital matrix switch used to route the modulated output signals to an amplifier as a function of their type. The programmable digital matrix switches make it possible to address constraints regarding the segregation of varying numbers of input/output signals of different types. ## Claims ### Claim 1 An electronic circuit card for a system for acquiring and generating signals, comprising: (1) means for conditioning input signals of at least two types chosen from the following types: digital, discrete, and analog;
