1. Design a MOD-5 synchronous counter using JK flip flop and implement it. Also construct a timing diagram.
6. A sequential circuit with two D flip flops, A and B; two inputs x and y; and one output z, specified by the following next state and output equations. An+1 = ¯y + xAn Bn+1 = ¯Bn + xAn Z = Bn (a) Draw the logic diagram of the circuit (b) Derive the state table (c) Derive the state diagram.
