Implement the following Boolean function with a 4 x 1 multiplexer and external gates. Connect inputs A and B to the selection lines. The input requirements for the four data lines will be a function of variables C and D. These values are obtained by expressing F as a function of C and D for each of the four cases when AB = 00, 01, 10, and 11. These functions may have to be implemented with external gates. F(A, B, C, D) = E(1, 3, 4, 10,11, 12, 13, 14, 15)

1.) Design/draw a (4) bit adder and subtractor Reference your lab 11 Show the logic steps to operate: 2. ) Math Operation: Binary 9-4 =___________   For example: Show the inputs to the EXOR gates A0-1-2-3  = B 0-1-2-3 = CTRL = A/D   Outputs of  (Adder: 7483) S0= S1= S2= S3 =_____

A state machine produces consecutive outputs, at each rising edge of the clock, in the following sequence. A B 1 1 0 1 then repeating 0 0 etc The state transition logic in this system may be implemented by the logic circuit shown below. This circuit is designed using two D flip-flops as well as two logic gates referred to as i and ii in the figure below. ii 1D C1 B 1D C1 CLK a) What is the function of gate i? Please select your answer among the choices given below. Recall that a NOR-EXCLUSIVE gate is an OR-EXCLUSIVE gate with an inverted output, i.e. an OR-EXCLUSIVE gate followed by a NOT gate. O NOR-EXCLUSIVE O NAND O NOR Submit part Unanswered b) What is the function of gate ii? Please select your answer among the choices given below. O NAND O NOR-EXCLUSIVE O NOR Submit part Unanswered
