1. In the simulation run of the four-bit adder, when we performed the additions of 2 + 4 and 3 + 6 we did not immediately have an output of 6 and 9 respectively on SOUT. What could be the cause of this?
2. If we changed the count period to 100ns for AI and BI would this correct the anomalities? why or why not?
3. How fast can your 4-bit adder/subtractor determine the sum or difference of two numbers?
4. Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1 (if 1st byte is closest) or ..
Assume the z0 is in the far field and derive an expression for the strength to return as a function of angle. Make approximations where appropriate and do not forget the sidelobes.
A coaxial cable has a loss of 5.6 dB at a frequency f. A signal at f has ans rms amplitude of 1.7 mV at the cable input. What is the rms amplitude after it has traveled the length of the cable
The total charge that has accumulated on the positive plate of a capacitor varies with time. The charge follows q=At^2 for the first 4s. a) Find the value of current at t=2,6,9,12,16 s. b) Sketch the current i(t) as a function of time
A transformer has a primary voltage of 115v and a secondary voltage of 24v. If the number of turns in the primary is 345, how many turns are in the secondary?
Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization curve.
Electrons in silicon carbide have a mobility of 1000 cm^2/V-sec. At what value of the electric field do the electrons reach a velocity of 3 X 10^7 cm/s Assume that the movility is constant and independent of the elctric field.
The NMOS transistors in the circuit shown in Figure P16.68 have parameters Kn =0.2mA/V2,VTN =0.5V,λ=0,andγ =0.(a)Forgatevoltagesof φ = 2.5 V, determine the quasi-steady-state output voltage for (i) vI = 0
the worker's safety harness D-ring is attached to a 12-foot shock absorbing lanyard that is securely fastened to the structure at a point 40 feet above ground level. Does this arrangement violate OSHA standards for fall protection? Explain.
algorithms to show the differences in the intra prediction in the h.264 and hevc coding standards. it should indicate how the intraprediction in the two coding standards makes a difference in their efficiency.
Design a 4-bit decrementer using Half-adders and inverters as building blocks. The circuits impleents A-1=S. Draw the circuit diagram. Hint: consider addtion of the 2s complement of -1 =1111. Begin with a 4-bit adder circuit constructed with 1-bit..
Design a circuit that might be used as a trigger for a night-light. You are given a photoresistor whose resistance changes from 5k when inside a lighted room to 30k in a dark room. Design a voltage divider circuit that will provide a 3V
