FUNCTIONAL UNIT, AS WELL AS STRUCTURAL ARRANGEMENT COMPRISING THE FUNCTIONAL UNIT AND PERIPHERAL SYSTEM

摘要

The present invention relates to a functional unit and to a structural arrangement and peripheral system comprising the functional unit. In the functional unit according to the invention, in the amplification mode in which the signal processing switching unit (7) does not supply power to the functional unit (5), the signal unit (8a, 8b) is connected to the circuit (8a, 8b) of the functional unit (5) via the signal line on the basis of which the circuit (8a, 8b) generates an amplification signal indicating to the signal processing clock switching unit (7) the type of the functional unit (5), which is transmitted to the signal transmission unit 7 via the supply line (10). In an arrangement with several functional units, each functional unit has its own signal line (12a, 12b) and circuit (8a, 8b), but the power supply lines (10, 11) are common.The peripheral system comprises a plurality of functional units (5) which are the first interrogator signal. (6a) and the second input signal generating input operators (6b).
