1. Explain the process to convert an analog signal to a digital one.
it done by recording and taking samples of the analogy signals to be digital, the more samples taken within a specific time frame the higher the quality and the closer it is to the original
2. Encode your first name into bits using the ASCII encoding table in figure 1.9 Omar ->-> O > 100 1111 , m > 110 1101 , a > 110 0001 , r > 111 0010
3. Convert the following binary numbers to decimal numbers:
- 101 > 1+4= 5 base 10
- 001 > 1 base 10
- 1010 > 2+8= 10 base 10
- 1110001 > 1+16+32+64= 113 base 10
- 10101010 > 2+8+32+128= 170 base 10
4. Convert the following decimal number to binary numbers:
- 3 > 11 base 2
- 15 > 1111 base 2
- 16 > 10000 base 2
- 34 > 100010 base 2
- 93 > 1011101 base 2
5. Convert the following octal numbers to binary numbers:
- 7 > 111 base 2
- 12 > 1010 base 2
- 23 > 10011 base 2
- 26 > 10110 base 2
- 38 > Can't, because octal only gets to 7 or is it within (0,1,2,3,4,5,6,7)
6. Convert binary octal numbers from exercise #7 to hexadecimal
- 111> 7 base 16
- 1010> A base 16

8. Convert the hexadecimal numbers from exercise #9 to octal
- 3 > 3 base 8
- 1B > 33 base 8
- CA > 312 base 8
- 01DE > 736 basse 8
- FADE3 > 3726743 base 8
9. Describe the concept know as Moore's Law
>> Moore's law goes back to Gordon Moore in 1965 as he noticed that the number of transistors have doubled since it was invented, and he predicted it would continue to do so in the future.
10. Explain the behavior of the nMOS gate nMOS is a transistor that works like a switch, if the value is "1" then the gate would be "ON," and "0" would be "OFF"
However, pMOS is the other way around
11. Evaluate the equation: F = (a)' OR (b AND c) for the given values of variables:
- a = 1, b = 1, c = 1
- a = 1, b = 0, c = 1
- a = 0, b = 1, c = 0
- a = 0, b = 0, c = 1
- a = 1, b = 1, c = 0
12. Use algebraic manipulation to convert the following equation to sum of products from: (Explain which properties used)
- F = (a + b)c + cb'
13. Use DeMorgan's Law to find the inverse of the following equation:
- F = ab + c
14. Convert the following boolean equations to a digital circuit:
- F(a,b,c) = ab + c
- F(a,b,c) = a' + ab + c' + b
15. Convert the following Boolean equations to canonical sum-of-midterms form:
