From the  choices below select the one which implements 4-bit Ripple carry adder with minimal resources.

Find the expression for Output given this truth table.

Consider only Full adders:

To add two 17-bit numbers, how many full adders should be connected in cascaded way?

Convert the given 8-bit two's complement binary number to its equivalent decimal.

1101 0011

Convert the given 8-bit two's complement binary number to its equivalent decimal.

1010 1111

Convert the given 8-bit two's complement binary number to its equivalent decimal.

0010 1111

Convert the given 12-bit two's complement binary number to its equivalent decimal.

1011 0101 1001

In Carry Lookahead Adder, carry will propagate if Carry In =1 and the resulting Carry Out = 1.

Full adder computes the Sum by taking XOR of the three inputs.

Full Adder and Full Subtractor can be implemented by their corresponding Half Adder/Subtractors (2 of them) and 1 OR gate.
