10 Questions
What is the main difference between synchronous and asynchronous state transitions in flip-flops?
State transitions occur independently of any clock in asynchronous transitions.
What is the primary function of flip-flops in digital circuits?
Act as bi-stable multivibrators
How are latches different from flip-flops in terms of input sensitivity?
Latches are sensitive to the duration of the pulse, while flip-flops are not.
What is the purpose of the R (RESET) and S (SET) inputs in NAND-NOR latches (SR latches)?
Facilitate the basic storage element
What characteristic defines Q and Q' outputs in NAND-NOR latches (SR latches)?
They are never equal to each other and complement each other
What is the additional input in a gated latch called?
Enable input
What is the simple rule for the D latch?
Q follows D when the Enable is active
What type of flip-flop changes state either at positive or negative edge of the clock pulse?
Edge-triggered flip-flop
What type of flip-flop requires a complete pulse (0→1 →0) in order to change the output?
Pulse-triggered flip-flop
What are data lock-out flip-flops also known as?
Data latches
This quiz covers the concepts of flip-flops in digital circuits, discussing the differences between synchronous and asynchronous state transitions. It explains the role of flip-flops as building blocks of sequential circuits and their connection to bi-stable multivibrators.
