Exam #2 – Practice PROBLEM 2 (1 point) What is used to select one of many inputs? A. Decoder B. MUX or multiplexer C. Full adder D. Inverter E. R-S latch PROBLEM 3 (1 point) Circle ALL of the following elements which are sequential logic circuits: Decoder Full Adder Master-Slave Flip-Flop D-Latch Register Inverter (NOT gate) R-S Latch Multiplexer (MUX) None of these PROBLEM 8 (4 points) The following figure shows the waveforms of input Data “D” and Write Enable “WE” of a gated D latch. Draw the output signal of the latch (assuming it’s initial value is 0). If the output during a period cannot be determined, write “error” in that section. PROBLEM 10 (1 point) The PC is incremented so that during the next instruction cycle, the next instruction will be processed. This happens during the PROBLEM 11 (1 point) In the FETCH phase, an instruction is transferred from memory to the PROBLEM 14 (5 points) Draw a gate level circuit (using just AND and OR gates with appropriate inverting/NOT inputs) to implement the following truth table with inputs X, Y, and Z, and outputs U and V. (The table does not necessarily represent any particular operation! It’s fine not to draw all the connection lines as long as all inputs and outputs are clearly labeled.) D out WE 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
