EE 110 Midterm: EE 110 NAU EExam 110 Probs208
Document Summary
Ee 110 practice problems for exam 2, fall 2008: circle t (true) or f (false) for each of these boolean equations. (a). (b). (c). (d). (e). Even parity means the data has an even number of bits that are 1 . If a decoder has 16 outputs, it requires 3 inputs to choose all possible outputs. Latches are edge-triggered memory devices: signed arithmetic: Find 3510 7210 using two"s complement format with 8-bit numbers. Find 6510 2510 using one"s complement format with 8-bit numbers. Add 6510 + 7210 using 8-bit sign-magnitude format for the numbers. Design a circuit that counts the number of 1"s present in 3 inputs a, b and c. its output is a two-bit number x1x0, representing that count in binary. Find the minimized logic equations for outputs x1 and x0; use a k-map if needed. Draw the corresponding logic diagram for this circuit. Draw a block diagram of a 4-to-1 multiplexer.
