Consider the following statements associated with the use of various a...
- Serial adders are used where circuit minimization is more important than speed because they require one clock pulse for each pair of bits added and hence slower than parallel adders. Thus, statements 2 and 4 are not correct.
- Statements 1 and 3 are correct.

Consider the following statements associated with the use of various a...
Incorrect statements:
2. Serial adders are used where speed is more important than circuit minimization.
4. Serial adders are faster than parallel adders.
Explanation:
1. A ripple carry adder is a parallel adder in which the carry-out of each full-adder is the carry-in to the next most significant adder.
A ripple carry adder is a type of parallel adder where the carry-out of each full-adder is connected to the carry-in of the next most significant adder. This means that each stage of the adder has to wait for the carry from the previous stage to propagate through, resulting in a delay. While this type of adder is simple to implement, it is relatively slow due to the ripple effect of the carry propagation.
2. Serial adders are used where speed is more important than circuit minimization.
This statement is incorrect. Serial adders are used where circuit minimization is more important than speed. Serial adders process the bits of the numbers sequentially, one bit at a time. This reduces the hardware complexity but increases the processing time as each bit has to be processed sequentially.
3. The look-ahead carry adder speeds up the process by eliminating the ripple carry.
The look-ahead carry adder is a type of parallel adder that speeds up the addition process by eliminating the ripple carry. It uses additional logic to generate all the carry signals in parallel, rather than waiting for the carry to propagate from one stage to the next. This reduces the delay and improves the overall speed of the adder.
4. Serial adders are faster than parallel adders.
This statement is incorrect. Parallel adders are generally faster than serial adders. Parallel adders process multiple bits simultaneously, which allows for faster computation. In contrast, serial adders process the bits sequentially, leading to slower processing time.
In summary, the correct statements are:
1. A ripple carry adder is a parallel adder in which the carry-out of each full-adder is the carry-in to the next most significant adder.
3. The look-ahead carry adder speeds up the process by eliminating the ripple carry.
Therefore, the correct answer is option C) 1 and 3 only.
2. Serial adders are used where speed is more important than circuit minimization.
4. Serial adders are faster than parallel adders.
