Here are the answers to your questions: QUESTION 10 B. Signal weakening over distance. Signal attenuation refers to the loss of signal strength as it travels through a medium, which is primarily caused by the signal weakening over distance. QUESTION 11 B. A Step 1: Apply the absorption law of Boolean algebra, which states that A + AB = A. Alternatively, factor out A: A + AB = A(1 + B) Step 2: Apply the Boolean identity 1 + X = 1. A(1 + B) = A(1) Step 3: Apply the Boolean identity A · 1 = A. A(1) = A The simplified expression is A. QUESTION 12 A. 0 Step 1: Substitute the given values A=1, B=0, and C=1 into the expression (A+B)·C. (1+0)·1 Step 2: Evaluate the term inside the parentheses. (1+0) = 1 Step 3: Evaluate the complement of C, C. 1 = 0 Step 4: Perform the final AND operation. 1 · 0 = 0 The evaluated expression is 0. QUESTION 13 C. AND gate. An AND gate produces an output of 1 only when all of its inputs are 1. If any input is 0, the output is 0. QUESTION 14 B. XNOR gate. An XNOR (Exclusive-NOR) gate gives an output of 0 whenever its inputs are different (e.g., 0 and 1, or 1 and 0). It outputs 1 when its inputs are the same (e.g., 0 and 0, or 1 and 1). QUESTION 15 A. NAND gate. The Boolean expression A+B is equivalent to A · B according to De Morgan's Law. The expression A · B represents a NAND gate. QUESTION 16 A. Identity law. The Identity Law in Boolean algebra states that A+0=A and A · 1 = A. The given expression A+0=A directly illustrates the Identity Law for the OR operation.
