Design a new type of positive-edge-triggered flip-flop called the LH flip-flop. It has a clock C, a data input D,and a load input L. If, at the positive edge of C, L equals 1, then the data on D is stored in the flip-flop. If, at the positive edge of C, L equals 0, then the current stored value in the flip-flop is held. Design the flip-flop using only latches, NAND gates, and inverters.
