Basic LAN Configuration - Practice Topology

Download the Cisco Packet Tracer file (.pkt) and configure the Laptops and Desktops so that they all can communicate with each other.

Download .pkt file

Rules:

1. Use your assigned IP address given in class.
2. Find  (a) Network address,  (b) Broadcast address,  (c) Total number of users,  (d) First user's IP address and  (e) Last user's IP address.
3. After the completion of configuration, use ping command to check connectivity.
4. Save the file and send it to me via Email (nsadat@live.com)   or   Facebook.

How to proceed:

1. Connect the Desktops and Laptops with appropriate cables with the switch. Use FastEthernet ports.

Welcome to students of EEE-2213 (Energy Conversion-2)

Dear students, welcome to my blog. Here you will find the necessary course materials (PDFs, Suggestions, Exam schedules, Results etc.) required for EEE-2213.

Given below is the syllabus of this course. We shall start with the 'Alternators' part.

• Alternators: Construction, Theory of operation. Armature windings, Alternator regulation, Armature Reaction and reactance. Two Reaction Analysis, Transient condition of Alternator. Losses and efficiency, Synchronising and load sharing of alternator.

Special Suggestion for Digital Communication (EEE-3217)

Study the following questions:

1. Detection Error Probability (Last Slide, Last Question)

2. Example 1.1, 3.3, 3.4 from B. Scalar  (pictures are given below OR you can read from PDF)

1.1

Understanding HDB (High Density Bipolar) Coding

High-Density Bipolar or HDB Coding is used mainly for Bandwidth compression. Using this coding system, we eliminate a large number of consecutive zeros and replace them with certain codes.

Here, HDB3 and HDB4 will be discussed.  Follow each step and you should have no problems understanding the process.

Bit pattern:   10100001100000100000101

Step 1: For HDB3, (3+1)=4 zeros and for HDB4, (4+1)=5 zeros will be replaced with code.

Solution of Chapter 4 (Corcoran)

Here's a full solution for Chapter 4 of Alternating Current Circuits (by Kerchner and Corcoran).
For Mid 2, it would be enough to do only the selected problems.

Thank you.

Power Point presentations for Digital Communication

All slides for Digital Communication will be uploaded in this post.

1. Presentation on Nyquist criterion, Aliasing, Reconstruction
We have discussed Nyquist criterion (impulse sampling) and aliasing effect in class. But, reconstruction of signal has not been discussed due to lack of time. Study it on your own. I shall try to discuss the topic before final exam if we get enough time.

Wiring Design and Costing Rules

Rules:

1. Each group will consist of 3 members. In case of insufficient members, 2 students can make a group.
2. Group members can be chosen according to mutual consent. There's no restriction in this case.
3. Every group will submit a unique Floor Plan and member list within 18.02.2014 (Tuesday). Floor Plan will be same for all 3 members of a group.
4. Rest of the calculation (Electrical Points, Conduit Run, Light Calculation, Conduit & Wire Calculation etc.) will be different for each member. 
5. Designs submitted by each member will be compared with each other for determining the best design. So, sharing one's designing plan with another is not a good idea :)
6. Final Submission deadline will be decided later.

 N.B: Floor Plan & Group Member List submission deadline: 20.02.2014 (Thursday).

Chapter 3 Solution Manual: Corcoran

Here's a full solution manual for chapter 3 of Corcoran. There are some confusing problems which you may avoid. I shall try to upload another version as soon as I can.

For Mid 1, it would be enough to do only the selected problems.

Understanding 'Leading' and 'Lagging' voltage and current : EEE-1213

1.      A normal sine wave can be represented as,

2.      If the waveform is shifted to the right or left of 0°, the expression becomes

          where theta  is the angle in degrees or radians that the waveform has been shifted.

3.      If the waveform passes through the horizontal axis with a positive going (increasing with time) slope before 0°, as shown in Figure 2, the expression is:
