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