A lossless TL with if the voltage a cross a load connected to lossless TL is 20 Vrms
and reflection coefficient is equal to KR = 0.7270°.
1. Find VSWR (S) for this TL.
2. Find the voltage and current scales.
3. Find the voltage and current at d=0, 1/8, 1/4, 31/8 and 1/2 using Crank diagram
and tabulate the results, including the distances and the values for maximum and
minimum voltage, current, i.e. Emax and Emin at dmax and dmin, respectively.
4. From Crank diagram confirm that S has the same value found theoretically
already in (1) above.
5. Use Crank diagram to evaluate the transmitted power.
6. Draw clearly the SWR pattern from d=0 to d=1/2 showing the maximum
and minimum positions in your plot.
7. If the load is changed to Zr= ZO how would the SWR pattern look like?
Why? Draw it clearly.
# i neeeeeed solve quicklyllllllly
(a) A thin-film layer of thickness d is composed of contacting upright cylindrical grains of radius r. If these columnar grains pack in a square array (in plane view) what is the packing factor for this film?
(b) Suppose smaller cylindrical grains exactly fill in all the interstices between the larger original grains to create a denser bimodal grain-size structure. What is the packing factor for such a film?
What is A.I.? Explain the four pillars of artificial intelligence with suitable
examples.

For a Emitter Stabilized bias configuration if
Vcc = 20V, Av= -1.8, lę = 4.84mA, Vce = 3.53V and B = 140

Suppose you had reduced a 32-variable Boolean expression using Quine–McCluskey algorithm to a 12-variable expression. For the generated simplified expression, you are required to implement it into a digital logic circuit. You can only use Programmable Array Logic (PAL) or Programmable Logic Array (PLA) devices.
Assume that we had selected a Programmable Array Logic (PAL) and a Programmable Logic Array (PLA) for you to choose between.
1. Using TICPAL22V10Z-25C (Programmable Array Logic)
2. Using PLUS173–10 (Programmable Logic Array).
Your selections among stated PLA and PAL must consider the following constraints:
• Complexity
• Flexibility
• Speed
• Functionality
• Cost
a 4 poles generator has a lap wound armature with 50 slots and with 16 conductors per slot. The useful flux per pole is 30 milli Weber.Determine the speed assuming the machine must be driven to generate an e.m.f of 240 volts.
