Consider a system with the following transfer function,

G(s) = 10/ [s(s + 1)].

Design a compensator according to the following design objectives:

• Kv = 20 sec−1 ;

• PM = 50 oF;

• GM ≥ 10 dB.

Submit your answer regarding the detailed compensator design procedures, and the corresponding MATLAB code and figures to verify your design.

In addition, compare the step response of both uncompensated and compensated systems in MATLAB

Asychronous Counter Design a counter 5 to 15, FF JK or RS

Design a PLC ladder logic program to implement an automatic Car-Wash process. The system should have a
start and stop pushbuttons. When a Car enters the washing skid, a load cell switch is activated and the
following sequence is performed automatically:
1. Soaping for (20) sec through soap nozzles
2. Washing for (120) sec using big brushes
3. Rinsing for (60) sec using water nozzles
4. Drying for (40) sec using air nozzles
After finishing this process, the washing skid is moved out through a conveyor belt (motor) until a stop limit
switch is activated.

Can you please just answer part 2! Thank you

1. Suppose x(t) is a square wave of fundamental frequency 1000 rad/s. It gets processed by an ideal low-pass filter with cut-off frequency 1200 rad/s. Sketch the output of this filter, y(t). Suppose we want to process y(t) digitally and be able to fully reconstruct it. What is the minimum necessary sampling frequency to do so?

2. Suppose we wish to digitally process and fully reconstruct the same x(t) from before. Would it be a good decision to keep the low-pass filter? Why or why not? Would it be possible to fully reconstruct x(t)? If so, what is the minimum sampling frequency necessary to do so?

QUESTION 1

1. What is NOT a solid reason to recommend sputtering in Argon instead of e-beam deposition?

   	1.	You want purer films with no trapped inert gas.
   	2.	You want better film adhesion.
   	3.	You want to deposit a multicomponent film like, TiW.
   	4.	You want better step coverage.

QUESTION 2

1. What is NOT a solid reason to recommend e-beam deposition of aluminum over sputtering in Argon?

   	1.	We want the higher throughput (# wafers processed per hour) offered by e-beam deposition.
   	2.	The high temperatures required to get an acceptable deposition rate will scorch the aluminum film and degrade its resistivity.
   	3.	We want to avoid damaging the wafer by exposing it to a plasma.
   	4.	We want "line of sight" deposition to create special features that rely on portions of the wafer being blocked from deposition.

(Use Smith Chart) A 50 Ω line is terminated by a 75 Ω resistor. The input terminals are connected to the output terminals of a 30 Ω line. Both lines are 0.12 λ long.

a. Find Zin and Γin at the input of the 30 Ω line

b. SWR values on both lines

5. What are two methods to generate single-side band AM signal. If the modulating signal (message) has DC omponent, which method you will choose? Why?

could you please answer this in a complete brief explanation?

Two parallel connected loads take a total of 2.4 kW, with a 0.8 line delay at 120 Vrms and 60 Hz. One load absorbs 1.5 kW with a fp delay of 0.707.
Determine:
a) The fp of the second charge
b) The parallel element required to correct the fp of the two loads and convert it to a delay of 0.9

A 45-MVA, 13.8 kV synchronous machine is operating as a synchronous
condenser, as discussed in Appendix D (section D.4.1). It’s short-circuit ratio
is 1.68 and the field current at rated voltage, no load is 490 A. Assume the
generator to be connected directly to an 13.8 kV source

a. What is the saturated synchronous reactance of the generator in per unit
and in ohms per phase?
The generator field current is adjusted to 260 A.
b. Draw a phasor diagram, indicating the terminal voltage, internal voltage,
and armature current.
c. Calculate the armature current magnitude (per unit and amperes) and its
relative phase angle with respect to the terminal voltage.
d. Under these conditions, does the synchronous condenser appear inductive
or capacitive to the 11.5 kV system?

Assume that you are using a piezoelectric material to build a micro/MEMS actuator beam in order to pick up a red-blood cell (with mass of ~1picogram or 10-12grams). If the dimensions of this actuator beam are length=100µm, width=10μm, and thickness=1μm, what is the minimal voltage you need to apply to this piezoelectric actuator in order to pick up the red-blood cell? Please write down all your assumptions used to estimate the voltage required.
