Which of the following statements about Mealy and Moore state machines is/are CORRECT?
These are standard Mealy/Moore properties: Mealy often uses fewer states; Moore outputs are state-based; conversion from Mealy to Moore is always possible with possible state increase; Mealy outputs depend on current state and input.
A state diagram has 8 states and a 2-bit input. How many possible input-labeled outgoing transitions can originate from each state?
Two input bits give $2^2$=4 possible input combinations, hence four possible transition cases per state.
Setup time of a flip-flop is defined as:
Setup time is the minimum time window before active clock edge where input data must stay constant.
In a universal shift register, the parallel load operation is performed when control lines select mode:
Universal shift register mode inputs select between Hold, Shift Left, Shift Right, and Parallel Load.
What is the maximum binary value represented by a 6-bit ripple counter?
$A 6-bit binary counter represents 0 through 2^6-1=63.$
