54.
The carry propagation delay in 4-bit full-adder circuits:
is cumulative for each stage and limits the speed at which arithmetic operations are performed
is normally not a consideration because the delays are usually in the nanosecond range
decreases in direct ratio to the total number of full-adder stages
