Ques:- What are set up time & hold time constraints? What do they signify? Which one is critical for estimating maximum clock frequency of a circuit?
Right Answer:
Setup time is the minimum time before the clock edge that the data input must be stable, while hold time is the minimum time after the clock edge that the data input must remain stable. Setup time is critical for estimating the maximum clock frequency of a circuit.
Ques:- Given a circuit, draw its exact timing response.
Right Answer:
To provide the exact timing response of a circuit, I would need the specific circuit diagram and details about its components (like resistors, capacitors, and their values) and configuration. Please provide that information for an accurate timing response.
