difference bit output of a full subtractor

carry bit output of a full subtractor

carry bit output of a half adder

Which of the following is correct for the operation of a gated D-type flip-flop?

The Q output is either SET or RESET as soon as the D input goes HIGH or LOW

Only one of the inputs can be HIGH at a time

The output toggles if one of the inputs is held HIGH

The output follows the input when the clock is enabled

Digital input signals A, B, and C, with A as the most significant bit (MSB) and C as the least significant bit (LSB), are used to realize the Boolean function F = m₀ + m₂ + m₃ + m₅ + m₇, where m_i denotes the i^th minterm. Additionally, F has a don't care for m₁. The simplified expression for F is:

A'C' + BC + AC

A' + C

C' + A

A'C + BC + AC'
