How many full adder would be required to add two binary number each representing decimal number up through 1000 inbase ten?

Assuming the numbers to be added are positive only, 10 full adders are needed. If handling negative numbers by 2's complement, 11 adders will be needed.


What is a parallel adder?

The adders discussed in the previous section have been limited to adding single-digit binary numbers and carries. The largest sum that can be obtained using a full adder is 112. Parallel adders let us add multiple-digit numbers. If we place full adders in parallel, we can add two- or four-digit numbers or any other size desired. Figure 3-9 uses STANDARD SYMBOLS to show a parallel adder capable of adding two, two-digit binary numbers. In previous discussions we have depicted circuits with individual logic gates shown. Standard symbols (blocks) allow us to analyze circuits with inputs and outputs only. One standard symbol may actually contain many and various types of gates and circuits. The addend would be input on the A inputs (A2 = MSD, A1 = LSD), and the augend input on the B inputs (B2 = MSD, B1 = LSD). For this explanation we will assume there is no input to C0 (carry from a previous circuit). Figure 3-9. -Parallel binary adder. Now let's add some two-digit numbers. To add 102 (addend) and 012 (augend), assume there are numbers at the appropriate inputs. The addend inputs will be 1 on A2 and 0 on A1. The augend inputs will be 0 on B2 and 1 on B1. Working from right to left, as we do in normal addition, let's calculate the outputs of each full adder. With A1 at 0 and B1 at 1, the output of adder 1 will be a sum (S1) of 1 with no carry (C1). Since A2 is 1 and B2 is 0, we have a sum (S2) of 1 with no carry (C2) from adder 1. To determine the sum, read the outputs (C2, S 2, and S1) from left to right. In this case, C2 = 0, S2 = 1, and S1 = 1. The sum, then, of 102 and 012 is 0112 or 112. To add 112 and 012, assume one number is applied to A1 and A2, and the other to B1 and B2, as shown in figure 3-10. Adder 1 produces a sum (S1) of 0 and a carry (C1) of 1. Adder 2 gives us a sum (S2)

How many full adders and half adders are requird to add two 4 bit words?

A full adder takes two inputs plus carry in and produces one output plus carry out. You need four full adders to add two 4 bit words. (No half adders required.)Or: for the lowest bit you can use a half-adder (no input carry).

How many people die from a Puff Adder every year?

It is difficult to provide an exact number of deaths caused by Puff Adder bites every year, as data may vary across regions. However, Puff Adders are responsible for a significant number of snakebite fatalities in Africa. Immediate medical attention is crucial in the event of a Puff Adder bite to minimize the risk of fatal outcomes.
