1. Block diagram design Example

17. You can force the inputs a, b, c, and d then vary the inputs of s0 and s1 and observe the output . Also you can use the new design as a module to design 8:1 MUX and so on … Also you can construct any combinational logic

21. Counter Design Using JK FF

23. 3 BIT Counter Using 3 JK FF If we set Jk = 11 the Output will toggle with Clk rising edge and the truth table of the output will be as the counter output

24. If the outputs are taken from Q If the outputs are taken from Qbar Up Counter Operation Down Counter Operation
