Digital Arithmetic Operations and Circuits - Technical MCQs

Q1:

The carry propagation delay in 4-bit full-adder circuits:

A is cumulative for each stage and limits the speed at which arithmetic operations are performed

B is normally not a consideration because the delays are usually in the nanosecond range

C decreases in direct ratio to the total number of full-adder stages

D increases in direct ratio to the total number of full-adder stages, but is not a factor in limiting the speed of arithmetic operations

ANS:A - is cumulative for each stage and limits the speed at which arithmetic operations are performed
