FANTASTIC video Exactly what I was looking for and a wonderful expression! You are my savior!
N value is taken wrong
Maam , can you please derive the half wave dipole feilds ? pls
pls reply
Will upload soon.

Next time, tell your students/viewers what these symbols mean instead of just reading these symbols.

Best video in my opinion
• Linear Convolution Using The DFT
Nice work Greetings from Eastern Arabia
in one reference i found the formula for radiation resistance is Rs = 80 Ω * (1 - 1.32 * (l / λ)²) * tan²(π * (l / λ)) .. but the outcome value is not the same with your described formula whats wrong here i really confused !!!!!
Hi,It would be the exact formula whereas what I have used would be after approximating.So there will be slight change in final value
@@raji2243 thats right
nice explanation.
thank you alot
How to find directivity mam
There is direct formula.
Can you explain to me how did you get the result of Zout?
how can I determine autocorrelation at a given real data?
madam can you tell me the text book of this question
Thank you very much🤍🤍🤍🤍🤍
very usefull.
Madam can you share WWTD pdfs
Thank you mam
mam if the N value is 5 or 6 then what is the matrix box for j&-j
Thank you very much madam🙏
Thankyou so much mam After searching alot , i found this at last moment ❤️
you just copying mam from book . No explanation nor step you solved. sorry to say but it is real
A complete explanation is not provided in this video as at that point syllabus was cut short. I will try to upload an elaborate video.
kuch smjhate nhi koi explanation nhi bus likhte jao derivation yaad kru kya
Thank you very much! Greetings from Chile
dear madam, I was confused where is 32.7 come from?
theta = cos-1 (square root(0.707)) = 32.7
Thank you for the explaination
Thank you very much
Tnq so much mam.. plz continues ur teaching...of problems solving..
Excellent ma'am
Can you do with initial conditions please
Ma'am in the approximate beam area formula in the last problem..I understood that theta HP is the half power beam angle ..but you didn't calculate the phi HP value because both are equal..is it always the same? Is there any case where both values may vary?
Phi plane and theta plane are the two principal planes. Approximately both can be the same, but the exact value will be different. There are formulas to find exact values as well.
@@raji2243 Okay mam.. thank you for your reply
Share notes mam
Awesome
Well explain thank u mam
Thnks mam❣️
Please mam
sorry about that. Really busy.
Can you help me in my assignment related to convolution in MATLAB
Hii mam
Summation limits are wrong
Thank u so much
Most welcome 😊
The idft gives Circular Convolution right?
Linear convolution
@@raji2243 idft is over the period 0 to N-1 that is also the period of Circular Convolution. For Linear it is negative infinity to positive infinity
@@MrAmalthejus If you consider N=maximum length of both sequences, it will give circular convolution. So in this example N=2 and without padding with zeros will give circular convolution.
Good topic and info
Can you provide this code in the description box?
Thankyou miss...usefull for ktu MW EXAM
Thank you
Welcome!
helped a lot during exam time that to last moment preparation thank you
I didn't understand the last step..i.e.30*2.44...how it came out of that equn...
Cin(2*pi) there is a formula for that.If you take upto 8 terms and solve that formula the value will be equal to 2.44.
