The Spectrum: Representing Signals as a Function of Frequency

[@Gabegabe48]

I have you to thank for my future. Thank you for all that you have done. I am truly indebted to your majesty. Sincerely,

[@luciogaribay4321]

Simple and straightforward. Thank you!

[@ItsChaucha]

What an explanation, lots of thanks from Spain

[@Dukt_Tape]

Thank you so much for this brilliant explanation!

[@vedanshet5443]

i have been searching for this vedio for whole 2 days !!!!!

[@josecarlosribeiro3628]

Congratulations Professor Van Veen for your ability and beautful presentation! Mary Christmans nas Happy New Year! Gos bless you! Jacareí -Sao Paulo-Brasil

[@abhiramanne9649]

Clearly explained thank you I've looked up sOO many things and this is THE best video

[@SciHeartJourney]

Thank you! This was very helpful. I have to remember that "Euler" is pronounced .

[@witoldsosnowski8735]

Thank you so much for this amazing video. It finally dispelled all my doubts!!

[@Enes-hr3hp]

This is like a medicine, thank you :)

[@GioGio-zt6el]

best explanation so far

[@josemuygay8851]

You just saved many hours of frustration. Can't thank you enough. Subbed

[@stoneshou]

Around 7:00 for why using a function of frequency is better than a function of time.

[@tharinduabeyrathna9498]

Some times we need these spectrums for analysing purposes. When we do things like amplitude modulation we need these spectrums.

[@bhaggyaumayanganasalwathur6102]

@@tharinduabeyrathna9498 I think, this one is used for the periodic signal asymmetric condition, and when we get symmetric waveforms we cannot use this form to get the frequency spectrum, I think, we need to use exponential Fourier series to get the frequency spectrum in periodic symmetric waveforms.

[@bjornolsson9103]

Thank you this was a great explanation!

[@fahadalahmad7660]

thank you Mr.Barry

Hi Morocco

[@aniksheikh902]

What do mean by negative frequency at 4:10 ? Can anyone answer? How can frequency be negative?

[@tharinduabeyrathna9498]

Its about the directions of wave forms wich have those frequencies

[@amishisharma7100]

you explain so well ! Thank you so much !!

[@jakestimson3451]

Thank you, legend.

[@juicymushroom7415]

Such a good explanation thank you.

[@DemShion]

Thanks a lot for this, it really helped.

[@shawnkhan2024]

which playlist did this video come from

[@alexandrosnikoloudis1905]

Is there any way to get the graph spectrum x(f) using furrier series(no complex numbers) ?

[@tharinduabeyrathna9498]

i think yes!

[@ashkrish7537]

Without complex numbers representing a signal in frequency domain does not make sense.

[@lamnguyentrong275]

a amazing representation and thanks god you are not indian

[@mhmdtjra6127]

Why 😂 you mean because of the accent

[@zarifnazmie238]

can the spectrum have negative value?

[@victorolusegun8528]

Kindly help out with this. Consider a signal given by: Y(t) = -4 + cos (2A10t - π/4) - sin ( 2π20t) I. Find the energy and power

[@cyberflaneur9127]

thank you, good explantion

[@aquadap219]

thanks for the video

[@sandeeptyagi2002]

Thanks sir for understanding

[@mitake_ran_love_moca]

Amazing!!!!

[@CodeAndCourse]

thanks alot

[@suntech7094]

great

[@victorcalata-gentil9113]

I'm on the spectrum!
