PURPOSE:To generate electronically a waveform equal to a chattering waveform generated by a mechanical contact by forming a fixed circuit. CONSTITUTION:Output A of noise generator 1 which generates continuously a white noise and output D of random generator 2 are supplied to gate circuit 3. Here, generator 2, controlled by pulse C from terminal P1, outputs an output waveform equal to chattering generated at a mechanical contact, i.e., varying in output level according to the time. Gate 3, on the other hand, determines the greatest crest value of the output waveform by a voltage arriving at terminal P2 and also determines the pulse width of white noise A by a pulse arriving at terminal P3 to output a fixed chattering output to terminal P4. Thus, the chattering waveform equal to the chattering waveform generated by the mechanical contact can adequately be generated. |
