sir,how the frequency deviation you got that formula?
please can you explain me.
Sir, we can used Ec.cos(wct+phi) for this derivation as well right?
thank you sir we wish you to teach us about wideband frequency modulation
and we really appreciate you for the good session you have taught us!!!

Can you turn subtitles on for your videos, I have a hard time understanding what you are saying
Sir we can use cosine carrier signals as well?
Explained so good
Your positive comments motivates me.
Teachers like me just wants positive comment from student.
Love from you guys means a lot to me.
My goal is to create largest community of engineers in entire globe. Please help me by sharing this playlist with your friends.
I think the carrier signal should be Ec cos(---) like this instead of Ec sin(---) at 4:21
Exactly
Exactly it is cos
Sir explain whole conclusion once gain at last what we have discussed it will help to remember us
Thanks for your suggestions
Sir is Em denoting amplitude part?
Like that of Am!?
Yup
no explanations on frequency deviation anywhere.
I think that should be maximum modulating freq instead of max freq deviation at 3:27
thank you
Does the amplitude of modulating signal contribute in the frequency deviation? If yes then how
change in frequency literally represents the change in amplitude, does it not. It's just that instead of relying on amplitude deviation we use frequency deviation bc of its advantages
Thank you so much sir
Your positive comments motivates me.
Fm signal is y(t) =Ecos(___) ??
is deviation ratio same as modulation index??
that's my doubt too
Sir kha kha se kuch bhi la the cos ko sin me sin ko cos me badal rhe
Sine and cosine don't define modulation dear. You can use any of this two.
Sir but deviation in kennedis book is k.Vm.fc
Thanks a lot🙏
Sir frequency swing kya hota h
good job....but presentation needs to b improved ....
I am searching for the reason why frequency modulation index can be greater than 1 so long but still not found 😞..... Not even here
Btw nice explanation.... What you sir explained
where can i get notes ..?
From my Android app Engineering Funda.
Link is given in discription of all my videos.
Wht is max allowed deviation
in the FM signal you used sin but there will cos
You can use both
There is no problem, sin and cos are the same function 90 degrees delayed from each other. The only thing you need here is a wave that oscilates in a certain frequency, which both sin and cos are fine to use.
please provide notes
Why do you have such a bad throat in every video it is a little unpleasant.
I wasn't well on those days.
