Suppose you have three push buttons connected to (B5, B6 & B7) and eight LED's connected to (Do D7): Write a program to flash ON the odd LED's if we press the switch B7 for 0.4s, flash ON the even LED's if we press the switch (B6 for 0.4s and flash ON all the LED's if we press the switch B5 for 0.7s.

Suppose you have two push buttons connected to ports (0 & 1) and four LED's connected to ports (6-9). Write a program to flash ON the odd LED's if we press the switch 0 for 4s, flash ON the even LED's if we press the switch 1 for 5s and flash ON all the LED's otherwise for 6s.

Design a 4-bit circuit with 2 outputs A and B. A is 1 if the input is divisible by 2 and B is 1 if the input is divisible by 3. Simplify A and B and implement the circuit.a. Draw KMAP for A and B and simplify them and then draw circuit

Question 1. Design a 4-bit combinational circuit for a 2’s complementer. The circuit generates at the output the 2’s complement of the input binary numbers.a) Complete the following truth table. A, B, C, D indicate the input binary number to be complement- ed using 2’s complement and W, X, Y, Z represent the output 2’s complement of the input binary number. The variable D is the least significant bit and A is the most significant bit of the binary number.b) Simplify the Boolean function W in its Sum-of-Products (SOP) form using a K-Map (you do not have to show the circuit) and provide its simplified Boolean expression.c) Show that the Boolean function W can be realized using exclusive-OR (XOR) gates and OR gates draw its corresponding logic circuit.d) Simplify the Boolean function Z in its Product-of-Sums (POS) form using a K-Map, provide its simplified Boolean expression and draw its corresponding logic circuit.
