Digital Arithmetic Operations and Circuits - Technical MCQs

Q1:

The carry propagation delay in full-adder circuits:

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

B decreases in a direct ratio to the total number of FA stages.

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

D increases in a direct ratio to the total number of FA stages but is not a factor in limiting the speed of arithmetic operations.

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