Title: Method for sampling analog reaction signals from systems
Inventor: PRUCHNIK HELMUT DIPL ING
IPC: G01M11/00
Filed: 1993-04-08
Abstract: The object of the invention, which relates to a method for sampling analog reaction signals from systems, these reaction signals decaying after a reaction time, after an excitation, the type and instant of which can be chosen, and being removed from the system and a sampling pulse chain being generated, through which values of the reaction signal at the instant of occurrence of the individual sampling pulses are determined as discrete values, is, in the case of very short reaction times of systems, to achieve a high resolution of the measurement of the reaction signal with a low power requirement of the measuring system, to allow simple adaptation to various reaction times and degrees of resolution and to achieve the possibility of electronic integration. This is achieved in that two pulse trains (A, B), in each case intrinsically equidistant, having different pulse frequencies are generated, in that the system is multiply excited using the lower pulse frequency, the reaction signal (B) of each excitation being sampled using the higher pulse frequency and a set of values for the reaction signal being generated from the totality of all the samplings. <IMAGE>
