How frequency domain topic should be taught in the academic course?

AI Thread Summary
The discussion emphasizes the critical importance of teaching frequency domain concepts, such as Fourier and Laplace transforms, in academic courses, particularly in engineering. Participants express concern that many educators lack effective teaching methods, often relying on generic PowerPoint presentations that fail to engage students. There is a call for improved instructional strategies to enhance understanding and interest in these topics. Suggestions include utilizing resources like MIT's open courseware to supplement traditional teaching methods. Overall, there is a consensus that better educational approaches are needed to effectively convey the significance of frequency domain analysis in various fields.

This is a soft question but I think it's a real fact.The Frequency domain has made revolution in the field of Mathematics,Physics,Digital Signal and image Processing etc. Some of concepts
which are very difficult to analyse in
spatial or time domain can be very easily understood in the frequency domain using the theorems like Fourier transform &series, wavelets ,Laplace transform etc.But my experience is that when it is being taught in the academic curriculum or course, it is not given as much importance as it has to be. Most of the teachers or professors don't know how teach this topic and students like us get hardly any knowledge about the frequency domain in academic course compared to discussions in the forum like the very useful

https://www.physicsforums.comSo I am requesting the scholars, eminent professors and researchers to give some guidelines or explanation so that students as well as teachers get to know how frequency domain topic should be studied and taught in the academic curriculum. And all of us would study this topic with interest.

It is too bad that the way you were taught Fourier/Laplace/etc. didn't work for you. As you say, it is an important topic. I am curious what your academic background is (your major, etc.) , and how you were taught the subject. Was it a full year class, a one semester/quarter class, or just part of one class?

I am an electrical engineer in the US and adequately learned these topics (with the exception of wavelets) from a more-or-less standard "signals and systems" course required of all EEs. For me, a mixture of doing pencil and paper work (including sketching signals in time and frequency domains), and using MATLAB to calculate and plot examples was useful. Knowing the basic theorems and using them to understand how things work really helped as well: here I am thinking about a shift in the time domain being equivalent to a phase ramp in the frequency domain, etc.

Well,I am doing under graduation in 4
years Electronics and Telecommunication
Engineering .We have semester pattern
system (2 semesters in 1 year).In the 3rd
semester, We have subject named
"Signals and Systems" under which the
above topic is covered.

Most of the teachers or professors don't know how teach this topic. They teach with the help of readymade PowerPoint presentations (e.g. for Laplace transform, single PPT which is mostly downloaded from
internet )and sometimes they take chalk
in their hand .So the students like us get
hardly any knowledge about the frequency
domain in academic course .

Sir I have added some information.please go through it.
 
Sequences and series are related concepts, but they differ extremely from one another. I believe that students in integral calculus often confuse them. Part of the problem is that: Sequences are usually taught only briefly before moving on to series. The definition of a series involves two related sequences (terms and partial sums). Both have operations that take in a sequence and output a number (the limit or the sum). Both have convergence tests for convergence (monotone convergence and...
