# Engineering project, K-maps and whatnot

1-Construct a  K-map for 2  outputs – YES, NO, with 3 inputs : (Personal opinion, Parents opinion, Friends opinion)

2-A bulb in staircases has two switches, one switch being at the ground floor and the other one at the first floor. The bulb can be turned ON and can be turned OFF by and one of the switches irrespective of the state of the other switch. The logic of switching of the bulb resembles.

1. Construct a truth table
2. From the truth table, construct the final function by using Miniterm.

c) Compare # c item with the output of K- map

1. e) Construct the logic circuit for each of the essential inputs and for the final output

3- A Boolean function f of two variables X and Y is defined as follows: f(0, 0) = f(0, 1) = f(1, 1) = 1; f(1, 0) = 0 Assuming complements of X and Y are not available, a minimum cost solution for realizing using only 2-input NOR gates and 2-input OR gates (each having unit cost) would have a total cost of

(a) 1 unit

(b) 4 unit

(c) 3 unit

(d) 2 unit

4- Draw the following function:

(a) M1 = (P OR Q) XOR R

(b) M1 = (P AND Q) NOR R

(c) M1 = (P NOR Q) Nand R

(d) M1 = (P XOR Q) XNOR R

5- For the output F to be 1, what are the input combination should be?

8-  Numerous functions must be performed by the circuitry of an elevator (open/close door, move up/down, light up/down indicator, and so on).

1. Construct a truth table
1. From the truth table, construct the final function by using Miniterm.
1. Compare # c item with the output of K- map
1. ) Revise the performance so that the machine offers at most one of four floors
1. Construct the logic circuit for each of the essential inputs and for the final output

9- Snerdley’s Automated Cafeteria orders a machine to dispense coffee, tea, and milk. Design the machine so that it has a button (input line) for each choice and so that a customer can have at most one of the three choices.

1. Construct a truth table
2. From the truth table, construct the final function by using Miniterm.

c) Compare # c item with the output of K- map

d) From the truth table, construct the final function by using Max-term.

e) Construct the logic circuit for each of the essential inputs and for the final output

10- Design circuitry to run a seven-segment display for one digit. The input consists of a four-bit digit (where each bit is an input line). The outputs are a, b, c, d, e, f, and g of the seven segment diagram (1 = light the segment, 0 = do not light the segment). From a truth table, write and simplify seven Boolean expressions. Then draw the seven minimal circuits. Note: There are only ten rows of input in the table corresponding to the digits 0 (0000two through 9 (1001two).
