4-bit binary full adder with fast carry
the second stage on S3. As long as A3 and B3 are the same, HIGH or LOW, they do not
influence S3. Similarly, when A3 and B3 are the same, the carry into the third stage does
not influence the carry out of the third stage.
Figure 10 shows a method of implementing a 5-input encoder, where the inputs are
equally weighted. The outputs S1, S2 and S3 produce a binary number equal to the
number inputs (I1 to I5) that are HIGH.
Figure 11 shows a method of implementing a 5-input majority gate. When three or more
inputs (I1 to I5) are HIGH, the output M5 is HIGH.
