Thnk u so much Ma'am for all these videos of analog communication and digital communication and optical communication ... I watched most of them and found them to be very useful These many videos with lot of intensity and the creation of such videos speaks volumes of hardwork that u have done .
madam, I have question on receiver section on QPSK. My question is why " raised to power 4" and why not " raised to power 2" if we raised to power 2 and then pass it BPF with 2f and then frequency divide by 2. then also we get same result.
Maam phase change that you speak about (10 as pi/4, 00 as 3pi/4, 01 as 5pi/4 and 11 as 7pi/4 ) is there any specific reason behind this or this is standard? Any way to deduce this by basic info that pi/4 is the phase change between two bits?
Yes I have explained that too with the diagram when I took sin cos both positive or both negative or one of them positive.. Happy to help you.. Thank you so much for your motivating comment.. Stay connected for upcoming videos..
√PsTb represents the amplitude and in PSK, the output does not depend upon the amplitude, rather the information of the signal is contained in the phase so you can neglect √PsTb..
mam in wavefrom of odd bit multiplied by cos,why u shifted phase by different amount and for multiplying even bit by sin u shifted by different amount how u shifted the phase and by what amount plz tell?
at 15:51, we are getting output kt*bo(t) but you are telling we are getting bo(t), you are skipping something, please explain so that I could understand completely, thank you
Maybe you are watching the video in auto quality. From the upper right side 3 dots chose 1080 pixel quality, it will be clear then. Otherwise you can take screenshot in high quality and then watch the video.

Crystal clear explanation 👍
These videos are way clearer than the lectures we get at uni
which university?
Fact
Thank you very much !! Your lectures are really helping me in my masters !!
Kindly recommend the book for digital communication
Introduction to Analog and Digital Communications by Haykin and Moher, 2nd Ed

Thanks you maam. I got it.
Ma'am in receiver, why we are not taking √(PsTb) in the equation of s(t) ?
√PsTb represents the amplitude and in PSK, the output does not depend upon the amplitude, rather the information of the signal is contained in the phase so you can neglect √PsTb..
@@VaishaliKikan okay maam thank you
Very good explanation mam🙏

very well explained... really helpful. thanks
Is this coherent detector or non coherent detector plz clear this doubt.
I love that energy 👌👌. Are you doctor
Thanks for your feedback and for connecting
I am still not having PhD degree
the step afte [ root2 Ps coswt+ root Pssinwt] is not clear.
can you please tell me what is written
Better video when you talk in Hindi

Mam where can i get notes for this all lec of digital communication

Superr class
When we raise S(t) by 4, is there a frequency increase or an amplitude increase in the overall received signal?
i dont understand but i am stilll like her
Plz explain how iq signals combine with these modulation techniques in rf communication
I am working on analog communication..
There you will understand it..

Nice explanation mam..😊 I understood very well
Happy to help..
Hope you will again visit the channel and get benefited..
Thanks for feedback 😊
Mam bodd{t}KT is coming in receiver what does KT represent mam?
K represent the number of cycle
T represent the particular instant
Thank you so much for your feedback

mam plz tell as soon as possible
Good explanation but written text is not clear its very untidy!
