Document Summary
Ee 110 practice problems for exam 2: solutions, fall. 2008: circle t (true) or f (false) for each of these boolean equations. (a). (b). (c). (d). (e). T fo an 8-to-1 multiplexer requires 2 select lines. (an 8-to-1 multiplexer requires 3 select lines). T fo a half adder has a carry input. (a half adder has no carry input). T fo if a decoder has 16 outputs, it requires 3 inputs to choose all possible outputs. Even parity means the data has an even number of bits that are 1. (a 16-output decoder requires 4 inputs to choose all outputs). T fo latches are edge-triggered memory devices. (latches are level-triggered memory devices): signed arithmetic: Find 3510 7210 using two"s complement format with 8-bit numbers. In 8-bit two"s complement format, 3510 = 001000112. In 8-bit two"s complement format, +7210 = 010010002; ip the bits and add 1 to get two"s complement of a negative number.
