TIP: Know how XOR works Write 1.11_2 as a base 10 expression What is the bit-wise AND of the following patterns: 1001 1111 0110 1001 What is the bit-wise OR of the following patterns: 0110 1111 0101 1110 Write the two DeMorgan's Laws and Distributive Law's Prove the Distributive Laws using truth tables. Use 2's complement to perform the following operations in 8 bits. Indicate if there is overflow. - 80 plus 57 - 112 plus -68 What is a combinational circuit? What is a D flip flop? What is the output of a D flip flop?

Explanation / Answer

8)Answer:

XOR:

The binary XOR (exclusive OR) operation has two inputs and one output. It is like the ADD operation which takes two arguments (two inputs) and produces one result (one output).

The inputs to a binary XOR operation can only be 0 or 1 and the result can only be 0 or 1

The binary XOR operation (also known as the binary XOR function) will always produce a 1 output if either of its inputs is 1 and will produce a 0output if both of its inputs are 0 or 1.

If we call the inputs A and B and the output C we can show the XOR function as:

The PIC machine code XOR instruction operates on 8 sets of inputs and outputs in parallel.

If we XOR two input bytes together on the PIC we get an output byte. If we give each bit within a byte a number we can see that each bit in the output is the result of the XOR function on two corresponds bits of the input.

9)Answer: 1.75

explanation:

1.112 in Binary number system and want to translate it into Decimal.
To do this, at first translate it to decimal here so :

1.112 = 120+12-1+12-2 = 1+0.5+0.25 = 1.7510

A B C 0 XOR 0 -> 0 0 XOR 1 -> 1 1 XOR 0 -> 1 1 XOR 1 -> 0
