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.
