The full diagnostic test for contact circuits in the presence of one-type contact faults (breaking or closure) is considered. We constructively establish that any Boolean function can be realized by a contact circuit permitting a non-trivial full diagnostic test, i.e., a test containing not all input vectors.

接触电路的诊断测试

考虑一种类型的接触故障（断开或闭合）时对接触电路的全面诊断测试。我们建设性地确定，任何布尔函数都可以通过允许非平凡的完整诊断测试的接触电路来实现，即，该测试不包含所有输入向量。
