| Abstract: | this paper introduces the design method of high speed collection and coding card ,which can be switched the simulation switch at random, it also can sampling randomly to multi-channel analog signals by A/D converter. In this paper, we analyse the characteristic of the traditional collection card, which processes of multi-channel analog signal, introducing the principle and design project of the collection card, describing the relation of each module and scheduling of module in detail. |
