  DSP, I think one of the easier subjects an electronics engineer studies. 😉 . Let's talk about all the concepts (dedicate a new thread for each of the new topic).

  This is one of the most interesting subject. I had a good score. Credit goes to my teacher.
  #-Link-Snipped-# Can you post us the question or syllabus to start a healthy discussion

  am very much interesting to learn the concepts of DSP/.lets starts CEans .............

  Jeffrey Arulraj

  The very first topic to differentiate the usage of Power in a signal and the Energy of a signal
  
  Though it seems very easy to think both are really important and different terminologies
  
  Can anyone find a proper explanation of this ?
  Next comes the role of each and every transform in DSP It may be Fourier or Z or Fast fourier any tries on explaining this is also welcome
  
  Answer tonight 😉

  Well no takers I guess
  
  We go for transforms like fourier and stuff only cause it is easy to represent a large signal in the time domain as a single frequency term in frequency domain
  
  Large signal in time domain implies Signal having infinite time period
  
  This in frequency domain has very small or single frequency

  Well 20 days hard work has paid at last a complete tutorial on the basics of DFT is ready will be posting it here in CE in the next month and we will have regular DSP classes really soon here in CE
  
  Portions to be covered
  
  Introduction to DTFT
  Properties of DFT
  Linear convolution
  Circular convolution
  DIT And DIF method of transformation
  
  Hope it helps all here in CE

  This will be one of the best thread.

  Okay
  
  I am sure we are not to be easily pushed aside this time this is truly learning and learners here we go Tomorrow we will be starting the first topic
  
  Things to be brought to class:
  

  • A little note to work some problems
  • A little basic idea about what a signal is
  • A little idea on power and energy of the signal
  • A little idea about Fourier

  Once you have this you are all set for classes from tomorrow
  
  PS: My datacard is not fit to upload resources so pls bare with me I can't do much this week only a small intro of DSP will be done

  Hello folks this is the beginning of a great series of tutorials for mastering DSP in a simple sense
  
  We are eager to have a healthy discussion here and all queries will be answered in this thread or in a thread you guys start
• 

  Jeffrey Arulraj

  Sorry about the error folks the pdf in the previous tutorial is inverted and so I heard that it was difficult to read
  
  I have done a little change hope it helps

  Jeffrey Arulraj

  Back to class now
  
  Class 2
  
  Well previously we must have learnt about transforms like Laplace transform Fourier series, Fourier transform, Z transform and stuff This class primarily concentrates on the relation ship between the transforms and DTFT Hope it helps

  Resource 2
  This tutorial primarily focuses on the relationship between DTFT and fourier series( both periodic and Aperiodic) and also the Z transform
  
  Hope it helps

  Sorry for Inconvenience due to jpg form resource

  Jeffrey Arulraj

  Pls note that the Fourier transform is completely different from the DTFT the reason is clearly pointed out in this thread
  Difference between Fourier transform and DTFT
