D flip-flop with asynchronous reset

WebThe set and reset are asynchronous active LOW inputs. When low, they override the clock and data input forcing the outputs to the steady state levels. In order to select this type of D Flip-Flop, select both the checkboxes for CLOCK and for SET/RESET (see the screenshot below). The symbol for this type of D Flip-Flop is the one below: Weba. The circuit is functioning properly. b. Q2 is incorrect; the flip-flop Q2 may be faulty. c. The input to flip-flop Q2 (D2) may be wrong; check the source of D2. d. A bad connection probably exists between ff-3 and ff-4, causing ff-3 not to reset.e. Both b and c are possible.
