Question HOMEWORK#3/ Digital Electronics II Please read carefully and analyze each question. The language used is simple and direct. If you find any questions not clear or confusing and you want to make assumptions, indicate the assumptions and state why the assumptions were made. Questions (1) Estimate the total number of states of the Intel 8085 microprocessor (2) Estimate the total number of states of the ACADEMIC SDK-85. (3) Estimate the maximum number of possible states of the SDK-85. (4) Discuss and compare a ROM FF with a RAM FF. (5) Define and discuss what is a von Neumann computer. (6) Define and discuss how the busses are used in a von Neumann computer. (7) Implement using hardware the Assembly instructions: MOV A,B and MOV B.A. (8) Implement using hardware the Assembly instruction XCHG (9) Implement using discrete electronic components the Assembly instruction ADD B, and indicate the circuitry that affects the F register. (10) Implement using discrete electronic components the Assembly instruction STA 2030 (11) Analyze the Assembly mnemonic program given below that starts at memory location 2000 (first RAM address): MVI C,20 MVIA B,20 MOV AC

2. Consider the closed-loop system in the following figure. RIS) + Sri S+ 3 Yrs) ka (a) Determine the closed-loop transfer function Y(s)/R(s). (b)Determine the steady-state error of the closed-loop system for a unit RAMP input r(t)=t for t>0. (c) Select a value for Ka so that the steady state error of the system response to a unit STEP function is zero.

1. (50 points) Given a core sample cores are cylindrical in shape) having a diameter of 3 inches and a length of 6 inches, you are to estimate porosity. Figure 1 shows two identical chambers having the same volume such that V1 = V2 = 1000cm3. These chambers are connected through a valve. First, chamber one is vacuumed and then pressurized to Pe = 50psig with helium gas. Next the core sample is placed in the second chamber and then again air is evacuated with vacuum and helium is supplied in the second chamber until the cell pressure is equal to the atmospheric pressure. Finally the valve is opened. Now the pressure in both chambers is equal to Pa= 28.1psig. Estimate the porosity of the core sample. Please comment on the results. V V₂ valve open valve closed gas supply Ра ie valve open Figure 1: Schematic of the system described in problem 1.
