[@umangrathore3696]

this is best tutorial for matlab i ever seen till now

[@MOANIS]

Please answer this :
x(t)=10+60sin(100*pi*t)+40cos(200*pi*t)+20cos(400*pi*t)
1- At first sight, what does the signal x(t) represent.What are its spectral components.
2- What is its samling frequency. Does it satisfy Shannon’s sampling theorem?
3- What can we say about x(t) if we compare it with a signal from Fourier series?

[@jadhavsourabh]

sir, how to change the amplitude?

[@asifraj321]

Brother requesting you to make a video to fit the data points with Fourier series of more than eight co-efficient

[@akramakbari5123]

Very helpful, thank you so much!

[@ElectroDeCODE]

Thanks.

[@alekyanaidu9789]

Can u explain how to awgn to a square wave

[@ElectroDeCODE]

There is function awgn() in MATLAB to add awgn to a signal. The video related to this will be uploaded soon

[@sumairaziz9219]

Informative video. Keep it up Sir

[@Abhishek-kq4qb]

Sir plz complex fourier series ke liye video banaoge

[@abdulbaseerphysicist2186]

sir can you help me in matlab

[@sarimansari9701]

Tum bohat mast kaam karta hay maqsood bhayi 🫂

[@ElectroDeCODE]

Thank You Sir

[@tarciodealmeidavieira1560]

If we change the dudy cicle in square function from 50% to 80%, what's change in fourier function?

[@HassanAli-fu7kj]

then it will remain 1 from 0 seconds to 1.6 seconds and -1 for the period betwenn 1.6 to 2. we need to change the code at the part of Integration to get it

[@Ayesha86_]

Thanks alot.

[@ElectroDeCODE]

👍

[@linley2036]

Thank you!

[@CourseMedia01]

what language you speak iam confused

[@_aniket.bhati_]

He is speaking Hindi, to understand better you can watch some other video in English

[@rahylkaouane7069]

Triangulaire please

[@sibtainulhaq9979]

Nice Sir 😃👍

[@ElectroDeCODE]

Thanks

[@ajaydebbarma858]

Please provide the code 🙏

[@fatimakhan2778]

Yes plz

[@fatimakhan2778]

We need some help for our research work
