Which of the following logic expression represent the function of 3 inputs XOR gate? Select one: O A. C(A'B+AB') Spar O B. AB'+AC'+BC+BC' O C. C(A'B+AB')+C'(A'B'+AB) O D. CA'B+C'AB' Synchronous counter operate at a higher frequency than a ripple counter. Why? Select one: O A. A ripple counter is faster Sher states are shore O B. The flip flops change their states at the same time O C. The flip flops change their states one after another D. None of them The minimum number of full adders needed in (3-bit multiplicand by 2-bit multiplier) multiplier is Select one: O A.2. Spark OB. 1 O C.3 O D.4 How many flip-flops are required to construct asynchronous counter that counts from 12 to 0? Select one: Spark O A. 12 O B.2 O C.4 O D.3 The minimum number of AND gates needed in (3 bit multiplicand by 3 bit multiplier multiplier is Select one O A6 Spark OB.5 O C.3 O 0.9 The Output is LOW if any one of the inputs is HIGH in case of a gate. Select one: O A. AND Spark OB. NAND O COR OD. NOR How many MUX we need to implement a truth table with 3 inputs and 4 outputs? Select one: O A.2. Spark OB. 1 O C.4 O D.3 How to represent -9 with signed one's complement "first complement" Select one: OA. 10001001 Spark B. 11110111 C 11110110 D. 11110011 The function F=X+X'y = Select one: Kipark B.
