Three 16 x 1 mux

Solution:

Which of the following accurately displays the Difference and Borrow expressions for a Half Subtractor?

Let D represent the Difference and Bo represent the Borrow. A is the minuend bit and B is the subtrahend bit.

D = A'B + AB' and Bo = AB

D = A'B' + AB' and Bo = AB

D = A'B + AB' and Bo = AB'

D = A'B + AB' and Bo = A'B'

Solution:

Select the option that best describes a Combinational Logic Circuit.

Signals move from the input to the output, in reverse direction with many feedback loops and in the absence of memory.

Signals move from the input to the output, in forward direction with many feedback loops and in the presence of memory.

Signals move from the output to the input, in forward direction without any feedback loops but in the presence of memory.
