The circuit assembly proposed includes a first and a second circuit (10, 11). Included in the second circuit (11) is a switch-in delay unit (35) which holds the first circuit (11) in the open state for a given period of time (T) after the two circuits (10, 11) have been put into operation. During this period of time (T), the signal at the output (40) of a signal processor (41) intended, for instance, for the measurement of a parameter occurring in the first circuit (10) is a quiescent-signal level. The quiescent-signal level is stored in a memory (38). On expiry of the given period (T), the quiescent-signal level stored in the memory (38) is used as a signal-correction value. Following each time the two circuits (10, 11) are brought into operation, a new correction value is generated, thus enabling long-term variations to be allowed for. |
