4.
Which binary subtraction is incorrect?
100101 - 100011 = 000000
10000000 - 01000000 = 1000000
10111110.1 - 101011.11 = 110010.11
11111111 - 1111111 = 10000000

3. A transparent latch is a D type flip flop
4. Master slave flip flop is used to store two bits of information
Which of the above are correct?
1, 2, 3
