What is Gaussian Noise?

Explains how Gaussian noise arises in digital communication systems, and explains what i.i.d. means.

The noise is gaussian because of central limit theorem

[naveenkmahendra]

Wow great video! In the world of so called professors, just read variables x's y's in their slides and leave their students in sheer confusion, this is how anyone should teach.

Great video. I got one question:
- What about the noise that is added during transmission of the signal? Is it also a gaussian noise?

[uralmutlu]

Quick question: the equation y=hx+n assumes that AWGN is added after the channel. what if part of the AWGN is caused by the transmitter electronics? then we will end up with y=h(n1+x)+n2, where n1 is the AWGN before the channel and n2 is the AWGN after the channel. We just assume that due to the central limit theorem, all the noise is modelled as a single AWGN value and added at the receiver. The question is: how do we model seperate noise sources? are there any reference where noise is added before and after transmission?
PS: the same discussion has taken place in the previous post....

thank you sir, love you from Vietnam 🇻🇳

You said that when we have stochastic process (here with the elactrons) with many realizations, we get a GAUSSIAN shape of the probability density function. Is there a special theorem that states that? Thanks

In Gaussian noise pdf curve the speediness of the curve occurs from which parameter. Explain the parameter and give details of the curve with help of example.

very clear thanks .I will watch all your videos

hello lain,
intigrator can be also viewed as low pass filter how can we relate this low pass filter operation with the collection of energy (the task performed by intigrator at the receiver)

[rkmangang]

The integrator ouput is no longer a function of 't'. How do you sample at t = kT?

[vaishnav]

Good explanation, Gaussian process and white noise comparison video please, is there any connection between those two ideas, please explain sir ..

[neetapriyangika]

Does this gaussian shape imply that there's high possibility for lower amplitude noise

[qazimashhood]

What is therm 'n' actually, is it the frequency, is it the amplitude. I am trying to understand this in terms of DSP though, and one thing more, how can we relate white noise to gaussian noise? Please help me understand this

[mrsureshkumarr-psgct]

Thanks for the beautiful presentation. can you make a video presentation on color and white noises? I subscribed your channel

[mallakbasheersyed]

Great one ! But where do we find these insights what would you recommend us to follow(and also what you are following) for these intuitions

[ihsi]

I hope i can speak english well to understand your lecture
