The piezoelectric adder unit comprises a monomorphic or bimorph piezoelectric element with three electrode systems, the first one of them is connected the first electric signal source, the second one is connected the second electric signal source and the third one is connected an output signal indicator. In the adder unit there is an inductance coil connected with common wires of three electrode systems and a signal source common wire and an indicator. |
