摘要：
The present invention concerns mechanical signal processing comprising a mechanical adder as a basic building block. Such a mechanical adder (40), which is a basic element of the present invention, comprises a first micromechanical member (40.1) being sensitive to a first frequency (f.sub.1) and a second micromechanical member (40.2) being sensitive to a second frequency (f.sub.2). The two micromechanical members (40.1, 40.2) are coupled via a linear coupling (41) to provide a superposition (sum) of the two frequencies (f.sub.1 and f.sub.2). Based on the adder, AND-gates and OR-gates can be realized by adding further micromechanical members and appropriate linear and non-linear coupling elements.
