Q1- For the latch in figure construct a next-state table and the characteristic equation. R- -Q H- D

what are the issues of the d latch

Figure 2.1 shows the input and the corresponding outputs of a flip-flop whereby QM and Q are taken from the Master latch and the Slave latch respectively. Give the full name of the flip-flop being used here and justify your answers. Use a block diagram for each latch, provide a circuit diagram of the flip-flop you have named. Input QM Q Figure 2.1

By only using D-type flip flops, you will need to: i. Show the state diagram of the counter from the previous specifications ii. Choose a Mealy or Moore machine and show the state table of the counter iii. Show the transition table for the counter iv. Show the excitation table for the counter with D inputs v. Write the simplified (use k-map) logic expression for the D inputs vi. Draw the circuit diagram
