Unformatted text preview: complement numbers. Perform the following operations and indicate whether overflow occurs: (2p) (a) A+B (2p) (b) A-B (2p) Give the decimal values of A and B 5. A computer has a word length of 8 bits including sign. Convert decimal +61 and +24 to binary using the signed 2s complement representation. Then perform the binary equivalent of (3p) (a) 24-61 (3p) (b) 61-24 (3p) (c) (-24)+(-61) Convert the answers back to decimal and verify that they are correct. 6. Using Venn diagrams, show that if A and B are sets, then (5p) (A+B) = AB (5p) X + XY = X (5p) 7. Suppose that a family of logic gates considers the output ranges of [0 - 0.2V] as 0 and [3.1V-3.3V] as 1. What are the reasonable input ranges for 0 and 1? (a) 0: [0.1 0.4V], 1: [2.3V - 3.3V]; (b) 0: [0-0.3V], 1: [2.8V - 3.0V]; (c) 0 : [0 - 0.5V], 1: [2.8V-3.3V] What are the noise margins for the reasonable output ranges above?...
