If the binary number 10100011 is ANDed with the mask 00001111, what is the result? 00000011 Floyd, Digital Fundamentals, 10th ed If you want to retain certain bits of a binary number but reset the other bits to 0, you could set a mask with 1’s in the position of the retained bits. Floyd, Digital Fundamentals, 10th edĪ B X The AND operation is used in computer programming as a selective mask. Thus, the AND operation is written as X = A. The AND operation is usually shown with a dot between the variables but it may be implied (no dot). For a 2-input gate, the truth table is Inputs Output A The AND gate produces a HIGH output when all inputs are HIGH otherwise, the output is LOW. All Rights ReservedĪ X A group of inverters can be used to form the 1’s complement of a binary number: Binary number © 2009 Pearson Education, Upper Saddle River, NJ 07458. Thus, the Boolean expression for an inverter is X = A. The NOT operation (complement) is shown with an overbar. When the input is LOW, the output is HIGH when the input is HIGH, the output is LOW. The inverter performs the Boolean NOT operation. 2008 Pearson Education © 2009 Pearson Education,©Upper Saddle River, NJ 07458.
