¿How can be achieved ?

There is no magic formula!E = m c2

So?

Criteria for a teaching philosophyThere must be clear objectives. Programs must demonstrate that at the

completion of theprogram students must have:

► Math, science and engineering skillsa) An ability to apply knowledge of mathematics, science, and

engineering b) An ability to design and conduct experiments, as well as to analyze

and interpret datac) An ability to use the techniques, skills, and modern engineering tools

necessary for engineering practice

► Project skillsa) An ability to design a system, component, or process to meet desired

needsb) An ability to function on multi-disciplinary teamsc) An ability to identify, formulate, and solve engineering problemsd) An ability to communicate effectively

► Context and Professional skillsa) An understanding of professional and ethical responsibilityb) A broad education necessary to understand the impact of engineering

solutions in a global and societal contextc) A recognition of the need for, and an ability to engage in life-long

learningd) A knowledge of contemporary issues

Teaching philosophy (continuation…)Before applying the teaching philosophy, it is

imperative to know what type of problems exist in engineering: Rote

► The rote problems tend to be easy to make up, and easy for the student to solve. All you need to do is change a few numbers and you have a new problem

Understanding► The understanding problems are very difficult to make up

since each one represents a new situation. They may be either easy or difficult for the students to solve.

Design► The design problems are easy to make up and very difficult to

solve. You can either change some specifications in the design problems in this text, or simply look around you to develop scores of interesting and challenging design situations.

With objectives and a clear criteria, then we can proceed to implement the teaching philosophy…

Find the Fourier transform of:

Find the convolution of the following signals (graphically and analytically)

All problems must be solved by hand and programming (e.g. MATLAB)

Write a MATLAB program that generates a transmitted carrier AM signal. Program must allow the user to specify the following parameters:

Carrier signal:

The parameters to be entered by the user are: A, B, fc, fm.The result must graph: The signal information, the carrier, and the modulated signal.

Information signal:

[·]2∑ LPFcos(2000πt)

2cos(4000πt)

y(t)

Find y(t) if the cut off frequency is 500 Hz.

Teaching philosophy (continuation…)HomeProject 3

Design an AM envelope detector. Once the detector is designed proceed to:(a) Simulate it in PSPICE (b) Code it in MATLABExecute the MATLAB program several times with different parameters and inputs and write a

conclusion of the results obtained.

A carrier with a frequency of 100-MHz is modulated with a sinusoidal signal of 75 KHz frequency in such a way that ∆f = 500 KHz. Find the approximate band of frequencies that occupies the FM signal.

Find the approximate band of frequencies occupied by the waveform:λ (t) = 100 cos (2π x105t + 35 cos 100 π t)

An FM stereo system is being designed for planet X, where the people have hearing that goes up to 25 KHz. La XIGET (Equivalent to the CIGET in El Salvador) has specified the band of frequencies between 100 MHz and 200 MHz for their broadcast FM. Each channel is allocated 200 KHz within this band. You are asked to design the FM stereo system. Describe, in detail, the changes you would make to the system we use on earth in El Salvador.

Assume that the system used in El Salvador is the one presented in chapter 5 of Dr. Roden’s book.

Teaching philosophy (continuation…)HomeProject 3 (continuation)

Design a FM demodulator (Discriminator detector). Once the detector is designed proceed to program it in MATLABExecute the program several times with different parameters and inputs and write a

conclusion of the results.

Write an article on how the process of design in part A. The format of the article must contain all the main sections that a professional engineering article consists of. As an example the article SideLobeApodization.pdf is facilitated. Do not limit yourself only to this example, find other examples. The article must not exceed three pages and should not only contain words. If the article is written in English then it could be weighted up to an 8%.

► Writing of articles could be based on: Seminars, conferences, and colloquies Projects Training (including graduate courses) Reading of magazines, journals, y transactions Research (simulations, design, implementation, etc.) IEEE writing format Students and professors Bilingual (English and Spanish)

Teaching philosophy (continuation…)Presentation # 1, 2 y 3

Will be about concepts presented in class and practiced in labs during the first, second and third period of the semester. Presentations should be in group and there will be a group grade. All members of the group are responsible for the presentation (format, body, Q&A, etc.). Presentation should be given in a no maximum time of 16 minutes per group.

► Presentation contributions: Writing of ideas Effective communication Teamwork efficiency Use and application of

engineering tools Freedom to innovate

Agreement of ResponsibilityThe students listed agreed to the following:

I, as student of Communication System, accept not to turn in any of the HomeProjects for the rest of the semester II of 2006. In exchange I compromise with a TOTAL RESPONSABILITY to take more challenging exams with a 20% weight, including but not limiting to the TRIO (Learn to learn, Capacity to write ideas, and Innovation with a focus on design).

I UNDERSTAND AND I AM CONSCIOUS that such decision of not turning in any of the HomeProjects is a personal decision based on lack of time or any other reason that are the results of my previous decisions such as the decision to enroll in n courses during the current semester, to mention one.

In addition, I UNDERSTAND AND I AM CONSCIOUS that it is NOT ETHICAL to neither make others responsible for the results of my decisions nor my obligations.
