| Q. |
The circuits of NOR based S-R latch classified as asynchronous sequential circuits, why? |
| A. | because of inverted outputs |
| B. | because of triggering functionality |
| C. | because of cross-coupled connection |
| D. | because of inverted outputs & triggering functionality |
| Answer» C. because of cross-coupled connection | |
| Explanation: the cross-coupled connections from the output of one gate to the input of the other gate constitute a feedback path. for this reason, the circuits of nor based s-r latch classified as asynchronous sequential circuits. moreover, they are referred to as asynchronous because they function in the absence of a clock pulse. | |
