FAIL-SAFE LOGICAL OPERATION CIRCUIT USING ELECTROMAGNETIC COUPLING |
摘要 |
A fail-safe logical operation circuit which includes a transformer (T) for converting binary input signals to magnetic flux to sum them up, and a level detector (1) for detecting this sum and generating binary outputs having logical values of "1" and "0". In this way, the fail-safe circuit can simplify the circuit construction and can reduce the level of the logical output. |
