Consider the following statements regarding combinational and sequential circuits.
(A) The output of a combinational circuit depends only on the current input.
(B) The output of a combinational circuit depends on both the current input and the previous output.
(C) The output of a sequential circuit depends only on the current input.
(D) The output of a sequential circuit depends on both the current input and the previous output (state).

Show answer & explanation
Correct answer: B. (A) and (D) Only
Explanation
Combinational circuits have no memory, so their output depends only on present inputs. Sequential circuits have memory, so their output depends on present inputs and the stored state.More Computer System Architecture questions
