DO HARDWORK To receive credit for this assignment, each problem must be computed using a MATLAB script. Do not hard-code computations. Define variables for the parameters given in the problem, and use MATLAB to calculate necessary intermediate and final output variables. Inlcude the MATLAB Code. A 200-mi. transmission line has the following parameters at 60 Hz: Resistance, r = 0.24 Ω/mi. per phase Series Reactance, x = 0.71 Ω/mi. per phase Shunt Susceptance, b = 5.42 × 10−6 S/mi. per phase Determine the signal wavelength λ and the propagation constant γ, attenuation constant α, phase constant β, and characteristic impedance Zc of the transmission line at 60 Hz using the general expressions in terms of Z and Y parameters valid for conductance G = 0 S/mi. Next, calculate the “convenient” artificial value for conductance G = RC/L and α, β, and Zc using this approximation. Finally, determine the sending-end voltage and current if the line is open-circuited and the receiving-end voltage is 100 kV line-to-line.

The torque generated by a PMSM by, is the (positive) magnitude of . If we control the angle  such that  , hence ,  then the PMSM becomes a Field Oriented Control BLDC motor generating the torque as .   On the other hand, the torque generated by a separately excited dc motor can be expressed by  (refer to lecture notes).   For permanent magnet DC motor, .

Develop a matlab script file to calculate the practical single phase transformer parameters. The program should ask the user to provide the following individually:

S_rated
V1_rated
V2_rated
With secondary shorted
P1
V1
With primary open
P2
I2

The program should calculate
Req
Xeq
Zeq

Gc
Ym
Bm

Make sure your code will pronmpt a message like: “Enter the real power at the primary winding when the secondary winding is shorted, P1=). Do the same for all parameters S, V1_rated, V2_rated, P1,V1, P2, I2

The program should return the outputs the form: “the shunt inductance susceptance, Bm=”,
do the same for all outputs.

Using Multisim

Verify the logic of the XOR and XNOR gates and compare to OR and NOR gates.

A) Orient the Word Generator and Logic Analyzer in the workspace and enter the appropriate settings. (BELOW)

B) To create the four gates you will need four 10K resistors and:

1) OR gate: a (7432)

2) NOR gate: an OR (7432) with an INV (7404)

3) XOR gate: a (7486)

4) XNOR gate: a XOR (7486) with an INV (7404).

C) Use outputs 00 and 01 of the Word Generator as inputs A and B for each of the four gates and connect them to the first two inputs of the Logic Analyzer.

D) Wire the outputs from the four gates to the next four Logic Analyzer inputs and connect each output to ground through a 10K resistor.

Fill in a Truth Table for each of the four gates

Word Generator

The pins 15…….0 go across the bottom. Double click on the Word Generator to get the Control screen and select the following settings: Frequency = 1 kHz Trigger = Internal Display = Hex (codes) Also SET to Up Counter before you enter ACCEPT to leave the screen.

Logic Analyzer

Select the following setting: Clock/Div = 16 From the setup screen, click on Clock SET and choose: Clock Source = Internal Pre-trigger samples = 160 Post-trigger samples = 160 Threshold = 2.5V Enter ACCEPT to leave the Clock SET screen. From the setup screen, click on Trig SET and choose: Trigger Clock Edge = Positive Trigger Qualifier = x Pattern A = xxxxxxxxxxxxxx Trigger Combinations = A Enter ACCEPT to leave the Trig SET screen

Suppose that x bits of user data are to be transmitted over a k-hop path in a packetswitched network as a series of packets, each containing p data bits and h header bits, with x >> p + h. The bit rate of the lines is b bps and the propagation delay is negligible. What value of p minimizes the total delay?

Assume that the header size (h bits) is NOT included in the data size (p bits)
