map1:
Draw a map, determine the simplified function and the network of the following truth tables:
The outputs are 1 to 010, 011, 110
The outputs are 1 for 0011, 0111, 1001, 1010
Mappa2:
want a keyboard with 4 keys encoder input (A, B, C, D) and three outputs (y1, y2, y3). If the button is pressed its bit is 1. If you have not pressed any button is pressed, or more than one key to all three outputs are always zero. The matches are A-001, B-010, C-100 and D-101.Dopo you draw the block diagram, mapping all three outputs while minimizing and calculating the Boolean expression. Finally, design the network of NAND only necessary to implement the desired functionality.
Mappa3:
want a keyboard encoder with 4-key input (S, A, B, C) and three outputs (y1, y2, y3). If the button is pressed its bit is 1. The key S is the schift and then must be pressed together with another key. If you have not pressed any button is pressed or the S key are pressed simultaneously alone or A and B or C, all three outputs are always zero. The matches are A-001 to-010, B-011, B-100, C-101, C-110.
After drawing the block diagram, mapping all three outputs while minimizing and then calculating the Boolean expression. Finally, design the network of NAND only necessary to implement the desired functionality.
Mappa4:
want a decoder that led pilots 4 and signals the presence of a code input. Assuming it has 4 inputs and the first LED lights with 0011, the second with 1100, the third with 1001 and the last with 000 draw a diagram Block, 4-output mapping by minimizing and then calculating the Boolean expression. Finally, design the network of NAND only necessary to implement the desired functionality.
Mappa5:
We want to design a multiplex with two channels A, B for data and a S for selection. Draw the block diagram, map the Boolean function, minimize it and draw a network of just Nand that implements the desired functionality.
Repeat for a demultiplex.
Mappa6: You want to build a network that signals the presence of a prime number, LED lights, when they are encoded on 4 bits input
Mappa7: Building a network with 3-bit input and 6 output bits which gives the square of the input binary number. Carried out only with Nand.
Mappa8: Design a circuit output signal with an LED if the input of 4 bits is a prime number or a number divisbile for 3. Carried out only with Nand.
