Description: All my filters – Analog, Digital and Adaptive
For private training
Many thanks for your helpful notes. I learnt a lot from it.
I have the FFT of my ideal filter impulse response and the FFT of my sampled baseband signal. Wha do i do next, in order to filter? Should i multiply the imaginary parts of the FFTs together and then plot in time domain?
Thanks for your well explained tutorials.
I would really appreciate it if you update the PDF file so I can use annotation tools in it, since I like to mark and add notes here and there in the file so I can find them later.
That would be of a great help to me.
I will start doing it shortly. If you are on Facebook page for Completoreal, you will see the notice.
Thank you for the comments.
Great mam… great work done by you. It is helping me learning my weakest part.
Hi Charan, Thanks for the great tutorials. In the “All my filters” tutorial, on page 2, you say “Writing the transfer function for the filter in Fig. 6.4.1” … but where is Fig. 6.4.1 ? Perhaps it was in an earlier tutorial, forgive me if I’m missing something obvious!
I’m in the UK and currently studying for a B-ENG in Electronic Systems Engineering. The Phase locked Tutorials fitted in really well. Thanks.
many thanks for this wonderful trove of comm. theory papers. I work for a ASIC/Systems company that is in the wireless comm field. And I have found myself referring to your tutorials time and again. This website really shows how comm. theory should be really taught to students who are aspiring to be engineers and not mathematicians.
I do have a question regarding the filter theory paper- in the section about MMSE equalization.
Specifically Equation 1.17 that specifies y(i) in terms of s(i) and n(i)
1) what is s(i). Is s(i) used in place of x(i) that was the original transmitted sequence of symbols
2) How would you know apriori the channel response s(i) + 0.5*s(i-1) + n(i) – are you assuming there are 2 rays caused by multi-path ?
3) Similarly Equation 1.24 is also confusing. How do you actually derive the equation 1.24. Could you please help explain further ?
