Show your solutions clearly and systematically. The D latch of Figure 1 is constructed with four NAND gates and an inverter. Consider the following three other ways for obtaining a D latch. In each case, draw the logic diagram and verify the circuit operation. D En D Next state of Q En 0 X 10 No change 11 Q=0; reset state Q-1; set state (a) Logic diagram (b) Function table Figure 1: D Latch 3. Use four NAND gates only (without an inverter). This can be done by connecting the output of the upper gate in Figure 1 (the gate that goes to the SR latch) to the input of the lower gate (instead of the inverter output). Q
