To expand a 4-bit parallel adder to an 8-bit parallel adder, we can
(A) use two 4-bit adders and connect the sum output of one to the input bit of the other
(B) use four 4-bit adders with no interconnections
(C) use two 4-bit adders with the carry output of one connected to the carry input of the other
(D) use eight 4-bit adders with no interconnections
Which of the following statement(s) about Digital-to-Analog (DAC) converter is/are correct?
(A) DAC is said to be monotonic if its output decreases as the binary input is incremented from one value to the next.
(B) Ideally, the output of a DAC should be zero when the binary input is zero.
(C) The operating speed of a DAC is usually specified by giving its settling time.
(D) Resolution is the reciprocal of the number of discrete steps in the full-scale output of the DAC.
