Abstract

PURPOSE:To obtain an output not subjected to level variation, by separating a plurality of input signals into frequency and amplitude components respectively for switching selection. CONSTITUTION:After a plurality of input signals S1-Sn are detected at a detection circuit 1, the frequency and amplitude components of each signal are respectively picked up at a frequency component pickup circuit 2 and a level detection circuit 3. The frequency component signal of each signal is selected at a frequency switching circuit 4 and the amplitude component signal is selected at a level switching circuit 5. Each selected signal is inputted to measuring devices and a signal synthesis circuit.
