Hatts off to you Sir🙌🔥🔥🔥 for this amazing Explanation
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.
last 2 graph are completely wrong
sinc^(fTb) is zero at +1/Tb , -1/Tb, +2/Tb and so on
del function will have impulse at 1/Tb , 2/Tb , .....
Your explanation is very clear. Thanks
Your positive comments motivates me, Thanks and welcome 🙏
Can anyone tell me the practical significance of studying these things...what will we do after knowing this only score cgpa and nothing else... education system should be more practical and project based..agree or not?
Not
@@Jichnahii
Can you tell me the practical significance of saying bad words to any one? What will you do after saying this only to feel momentarily happiness and nothing else... language system should be more soft and moral based..agree or not?
@@Jichnahii sbki apni apni thoughts hai bhai..koi baat nhi koi agree nhi kre to
@@fayequehannan2473 First one need to understand concept on how to work with anything.........
I agree with you partially bcz at least we know how to system works and in future demand will grow related these cocepts
@16:11..How the subtraction of 1 is removing the component of exponential term when n=0.Can anyone tell me?

Sir, thank you for the class.
If I were to apply the final formula to calculate the PSD of a pulse, should I replace f with the bandwidth occupied by a pulse?
At 16:46 , in the last step you were supposed to remove a square by 2, not 1
nice explanation🔥🔥

Thnk u very much sir.. this is very helpful🙏🙏
sir,it was help full,but what i need is the PSD of RZ line coding formats,because i denied them in any channel.
Gud clarification sir
Your positive comments motivates me, Thanks and welcome 🙏
sir your explanation is good , but i cannot do so much thing🙂
Excellent

Best lecture
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.
thank you very much i need the unipolar rz
Which book I refer this topic,Sir?
Sir please upload some gate question on power spectral density energy spectral please . Before gate exam
Sir, while you are finding the fourier transform of x(t) why you are not taking +a but 1.
signals multiplication has to be in freq domain.............
Thanks sir. 🙃

Very nice

zeros are at plus minus n/Tb not nTb
great...

Sir after multiplication of those two signals also we have a sinc tetm in the function. Why you are neglect the sinc term in the last expression?
Because after multplication the value at the y axis of sinc fn is 1 thats why only delta f remains there...
Why does the DC Component lead to distortion?
It doesn't have information and it consumes more power without information
@@EngineeringFunda
How do we know that it doesn't contain Information?
DC means no information.
@@EngineeringFunda
Why?
How one can have information with DC?
How the probability is equals to half , I can't understand , pls explain
thank yousir
Please share PSd of unipolar RZ
NAHIN PADHUNGA ENGINEERING . HUMSE NAA HO PAYEGA
ham aapke saath hain bhaiya
😭😭😭
Sabse jyada common kaunsa ata hain psd me
NRZ bipolar
Sir you have already taken care of n=0 condition so why are you again subtracting 1 from the summation term?
yes but n!=0 is still remaining i.e. summation from (n=negative infinity to positive infinity excluding n=0).since, infinity sum - e^0 =summation from (n=negative infinity to positive infinity excluding n=0).wkt, e^0=1. so, he used -1 there. hope this helps!
camera properly not set,
I HATE ENGINEERING 😭😭😭
Your f looks way too much like a t
