lets kill fme

[@meandkg]

I wasted 3 hours attempting to learn this from Sadiku's book. This video helped me in a total of 10 minutes (rewatching)
I can't thank you enough!

[@michaelivanhaileka9694]

haha me too Sadiku is complexed

[@Naharadir]

Professores indianos 4ever

[@moniquecastillo9746]

thank you professor shevgaonkar!!! best explanation ever.

[@ธนันธรรอดภัย]

thank you verymuch for Microwave engineering final exam . ขอบคุณ Prof.Shevgaonkar มากๆครับสำหรับการสอบในวิชา วิศวกรรมไมโครเวฟ ครับ (^ ^)

[@FREEPROGRAMS22]

You explained it to the fullest, chapter closed!! Thanks big!!!

What is the purpose of an "Admittance Smith Chart"? In this chart, the constant conductance g=1 locus is a circle in mirror image to the constant resistance r=1 locus in the "Impedance Smith Chart"; the latter chart is what is used in the video above.
While it seems intuitively reasonable that the constant r=1 circle would be equivalent to a constant g=1 circle, the very existence (downloadable) of the Admittance Smith Chart forces me to wonder WHY it exists, if it is not used in the above video... which is all about parallel connections, admittance, and compensation design via graphical technique.
...
Ah... I think I got it. The good professor is taking a short cut by using the classic (Impedance-form) Smith Chart, for both impedance calculations and admittance calculations. This saves him from the tedium of pulling out the proper Admittance Smith Chart, and re-plotting points that are already mapped on the classic Smith Chart.
Meanwhile, Professor Shevgaonkar deftly starts to speak about "constant conductance" where "constant resistance" used to be the identity of a circle. The rightmost point on the classic Smith Chart suddenly becomes a short-circuit locus (for admittance = infinity) rather than an open-circuit locus (for impedance=infinity). The hash marks along that describe wavelengths, exterior to the SWR=infinity circle, are uniform in spacing; since we are interested in subtractions of two loci, the answers are correct for length-of-transmission line and length-of-stub calculations.

thank you very much doctor. I just subscribed. I am a EE engineering student at the University of Houston.

[@thugstatZ]

watch cfurse smith chart videos

[@pragatins548]

Thanks it's very useful.

[@katokacks1113]

please help,my characteristic impedence is 20-j35 ohms and the length of the load is is 2.3 of the wave length.What will be the input impedance

[@SuperZeeka]

very helpful tutorial , thank you

[@engmido251]

thanks professor shevgaonkar

[@dominicpickford2496]

Thank you very much, this video is excellent, exam this afternoon :D

[@DeadEyeDillard]

Very helpful, thanks!

[@LukaGiga]

I had trouble understanding the speech at some points, but it's still a clear explanation.

[@mareknovak2245]

Very well done!

[@roycedsouza7803]

Thank you so much

[@MAFuncell]

thanks prof. (Y)

[@harshberiwal4123]

start from 2:20

[@DomsBeats]

Great video thank you :D

[@alexandrpetrov1110]

thank you!

[@RogerLuo1995]

Very good!

[@NitsVickyDalvi]

Thanks for the 6 marks🤐😉

[@alishibli4720]

THANK YOU ! ! !

[@shivaprasadk8714]

Very nice

[@AdrianMartinez-zw7ji]

Hi, great lesson, but what about if the admitance i inside de unitary circle what intersection can i take???
Greetings from Mexico

[@dhurbarajbhattarai7357]

Thanks for this but i want to know about double stub matching circuit

[@dl9ar245]

Does one have to consider electrical or the physical line lengths?

[@AJAYPALSINGH-wt6wd]

double stub matching can you please explain

[@vamsikrishna9501]

+Rushibmehta Which lecture from nptel of Prof. Shevgaonkar is it from?

[@PremalShah9393]

thanks :)

[@gehadali3597]

Can you tell me code to calculate Ls and L1 using matlab? Thanks in advance

[@파블로돈]

where is double stub?

[@rachmalind]

subtitle needed

[@srividyagalla1175]

for me its some what confusing !!!!

[@Tsachyl]

How can anyone understand that English? vy sad.

[@stormmetal777]

with subtitles switched on! :'DDD

[@ohmyfly3501]

Why are you dumb?

[@NehaGupta-nz4ol]

Tsachyl i can understand very well..

[@business-hy3lb]
