please help question 2
2. Design a half-adder with the constraint that you can only use NAND and NOR gates. The circuit inputs are two bits I and y and the outputs are the sum bit s and carry bit c. Draw a circuit diagram and label each input and output. 3. The digital circuit below contains a latch and two flip-flops. Use the wave forms provided to find Qa. Qb, and Qe. Assume that all three states have initial...

solve 1 2 and 3
Problems 1 and 2 require a 7-segment display. You may want to re-use the display driver you developed in Lab 3. Use a push-button as the clock - the pushbuttons are debounced, whereas the slide switches are not. Remember to provide columnsfor lest data in your state lables (use the observed next state as the test data in problems I and 2, and the observed next state and preseni output as the lest data in...

A retaining wall is to be constructed in a normally consolidated clayey sand deposit in the figure below. Ground water table is lmbelow the bottom of the excavation. A 20 kN/m2 surcharge pressure is applied over a wide area at the ground surface. Assume the wall moves into the excavation. Consider long-tem analysis (as it is usually the more critical analysis in excavation problems). Ignore capillarity as shown 20 kPa Clayey sand T17 kNm Y-20 kNm 5 m c'-10 kPa...
