2. A system for recording status sequences with application of signature analysis, whereas a high impedance detection circuit for the input signal is switched on the input of signature recorder is included at the signature recorder input, characterised in that the detection circuit (1) output is connected directly and at the same time indirectly via a NOT gate (2) to two inputs of a "straight/negated" signal selection circuit (3), whereas the detection circuit (1) control output is connected with the selection circuit (3) control input, whereas the selection system output is connected with the signature recorder (4) input and besides, the clock output is connected with the timing inputs of the detection circuit (1) and of the signature recorder (4).<IMAGE>
