Extracted text: Question 1) Figure Q1 shows a Carry Look Ahead Adder which can be designed from four (4) full adder. Addition of 4-bit number using parallel adder is difficult due to delay in the circuit. This can be overcome with the help of carry look ahead adder circuit. In this question you are required to add the below 4-bit number by using the Carry Look ahead adder shown below. a) The value of A = 1101 B = 1111 b) The value of A = 1111 B= 1011 A BO A1 B1 C0 Ao Bo Co a te A A ca Comb Ckt Comb Ckt Comb Ckt As Ba Ca A2 B2 C2 A1 B1 C1 Ao Bo Co Full Adder Full Adder Full Adder Full Adder C4 S3 C3 S2 C2 S1 C1 So Figure Q1
