Question
Observability in asynchronous sequential circuits is related to:a.The stability of the circuitb.The ease of inferring internal states from outputsc.The controllability of the circuitd.The predictability of circuit outputs
Solution
Observability in asynchronous sequential circuits is related to:
b. The ease of inferring internal states from outputs
Explanation:
Observability in the context of asynchronous sequential circuits refers to the ability to infer the internal state of the circuit based on its outputs. This is crucial in the design and testing of these circuits, as it allows for the detection of faults and the verification of correct operation.
In contrast, stability refers to the circuit's ability to maintain its state in the face of small disturbances, controllability refers to the ability to drive the circuit into a desired state via the inputs, and predictability refers to the ability to accurately forecast the circuit's outputs based on its current state and inputs. These are all important properties of asynchronous sequential circuits, but they are not directly related to observability.
