Abstract
The circuit arrangement serves to identify an input signal (s1) assigned to a predetermined signal class. It comprises signal-matching electronics (1) responsive to a current component and/or a voltage component of the input signal (s1) and providing a corresponding output signal (s2). By means of signal recognition electronics (2) of the circuit arrangement, the output signal (s2) is transformed into a recognition signal (c1) representative of the signal class.
Claims24
A circuit arrangement for identifying an input signal delivered from an external measurement device, said input signal belonging to a predetermined signal class, said circuit arrangement comprising:
- signal-matching electronics for the input signal which generate an output signal representative of
- a current component of the input signal and/or
- a voltage component of the input signal;
- and
- signal recognition electronics which derive from the output signal a recognition signal representative of the predetermined signal class of the input signal delivered from the measurement device.
A signal-processing unit for processing at least one input signal delivered from an external measurement device, said input signal belonging to a predetermined signal class, said signal-processing unit comprising:
- a circuit arrangement being coupled to said measurement device at least temporarily, wherein the circuit arrangement uses the input signal delivered from the measurement device to generate a recognition signal representing said predetermined signal class of said input signal delivered from the measurement device.
A data-gathering unit, comprising a signal-processing unit for processing at least one input signal delivered from an eternal measurement device, said input signal belonging to a predetermined signal class, said signal-processing comprising a circuit arrangement being coupled to said measurement device at least temporarily, wherein the circuit arrangement uses the input signal delivered from the measurement device to generate a recognition signal representing said predetermined signal class of said input signal delivered from the measurement device.
