Basic logic gates in digital electronics

• 2

• 1

• 4

• 3

Rule of AND Gate

• Outputs true (1) if at least one of its inputs is true.

• inverts the input

• Outputs true (1) only if all its inputs are true.

• Outputs the opposite value of its single input

Logic for calculating the factorial

• while(i<=n)

  f=f*i;

  i++

• while(i=n)

  f=f*i;

  i++

• while(i<n)

  f=f*i;

  i++

• while(i<=!n)

  f=f*i;

  i++

Logic of Odd and Even Number

• if(n%2==0)

• if(n/2=0)

• if(n%=2)

• if(n==0)

Role of OR Gates

• Outputs true (1) only if all its inputs are true.

• inverts the input

• Outputs true (1) only if all its inputs are true.

• Outputs the opposite value of its single input

Logic for finding the square root

• Use the Math.sqrt() function

• Iteratively subtract numbers until reaching 0

• Use the Math.pow() function with 0.5 as the exponent

• Divide the number by 2 until reaching the square root
