Sequential circuits

Sequencing elements are

• Latches

• Flip flops

• Shift registers

• Both A&B

clocked sequential circuits are

• Two phase overlapping clock

• Two phase non overlapping clock

• Four phase overlapping clock

• Four phase non overlapping clock

Sequential methods is not

• Pulsed latches

• Pulsed Flip flops

• Two phase latches

• Two phase flip flops

Minimum delay before any output starts to change once input changes

• Propagation delay

• Contamination delay

Sequential circuit includes

• only Delays

• Only Feed backs

• Delays and Feed backs from input to output

• Delays and Feed backs from output to input

The interval after the clock where the data must be held stable

• Setup time

• Hold time

When a clock signal is gated with another signal like load signal, output is not affected

• True

• False

Which is the delay elements for clocked system?

• AND gates

• OR gates

• Flip flops

• Multiplexers

Maximum delay after which all outputs are stable once input changes

• Propagation delay

• contamination delay

The interval before the clock where the data must be held stable

• Setup time

• Hold time
