第10题:
Sequential circuit is a common logic device whose output values, at a given instant, depend upon its input values and the internal state at that instant, and whose internal state depends upon the(66)preceding input values and the preceding internal state. A sequential circuit can assume a finite number of internal states and may therefore be regarded, from an abstract(67), as a finite(68).Combinational circuit is another logic device whose output values, at any given instant, depend upon the input values at that instant. A combinational circuit is a(69)of a sequential circuit whose internal state is not taken(70).
A.directly
B.immediately
C.instantly
D.snapshot
