i have them all. I just need to find the link for you
EDIT : I found it. here it is : Maloberti: http://ims.unipv.it/Microelettronica/Dataconverters1.html
Hello guys,
The total Noise floor that is given by the course I am enrolled now is :
Noise Floor = Man_made:noise+KTB-Noise_Margin-----(1)
here I think it is a mistake because for me the noise margin is a margin to have a security margin in case our signal drops below and should be written as...
Thank you both. Those two arrows are explained as that whenever we have a frequency d which is between certain value, with the violation of Nyquist criteria, we get a phase aliasing. my objective was to simulate that in Matlab for better understanding
I understood that. What I am trying to see is how the last 2 case introduce phase aliasing by itself. You did write the -PI/4 in the code, is t phase aliasing happening automatically in case 4 and f?

Thank you for your feedback.
what I am trying to see by simulating is the phase...
Thank you.
But the theory here says if I change the sampling frequency without changing f(must be set to 4 as constant) we should observe a phase conjugate due to low sampling rate
Hello Guys,
So after reading this article Sampling and Aliasing at page 30; I could not reproduce the where the phase has a conjugate value of the origial phase at Fs/2<f<Fs which result in :
fa = Fs − f, fa is the aliased frequency
Za = Z
so my code is here:
Fs1=30; % original sampling...
sorry for my late answer. Was very busy.
in the second case, you mentioned that :
Corollary, G < 1 then each time thru loop less and less is added
to Vs coming out of the summer, and ultimately the loop simple settles to Vs flowing
around loop, eg. stable.
I do not understand this correctly...
Thanks for your answer, Dana.
I am still confused about it.
First, if Vs=0 then Vo =Vs*A/(1-AB) which means A/(1-AB) must be different from 0,which means that AB #1!! so where I am getting wrong?
second, quote "
If you satisfied the angle criteria, 0, or N x 360 degrees (N is integer), but had a...
Hello everyone,
SO I am reading this article on negative feedback and the criteria to be stable.
I have not fully understood why if the loop gain at -180degree if the loop gain is less than 1 can be stable. why? because for me when the feedback has a shift phase of -180 and even the loop gain is...
