hmmm... i guess it makes more sense, i can't afford paying for Msc anyways. I dream of getting into caltech or mit, i know it's very very hard but i am going to try anyway, to be honest, tht polar vortex got me like " if i ever go there what am i going to do, i am very cold here and it's like 5...

well, in case i had to complete a Msc first, i guess maybe 29-30 and applying for a phD program. if i had a Msc from my home country and got a PhD in, let's say the us, will have a good chance of employment or will that Msc be a disadvantage

Is it possible as an electrical engineer to make a transition to data science? And is there R&D in this field ?

so to sum up, it will be much easier to get a degree from the country i like first then apply to a job it , couple of questions though 1- is age a factor? i mean if i apply when i am like early 30's , will my chances be less? 2- is better to get a Msc then a PhD or should i try to go for a PhD...

@Joshy @berkeman well...the thing is..i live from egypt xD A little about my country, we have ZERO R&D labs here, so no , unfortunately i don't have any work experience , i am planning to pursue this career abroad, probably europe since i already speak fluent english and french. I do have a...

I am going to graduate this year with a bachelor in electrical energy engineering, i am very passionate about designing and fixing problems, i would love to work in the R&D department of some multi-national company, but i don't know where to start. What qualifications do they usually ask for...

I got confused too when i was typing the reply , i will tell him to try it. Will parameter estimators ( like maximum likelyhood for example ) work?

So for example if i have a signal with period 6 s and i am taking a sample every 1 s Lets say 0 1 1 3 2 4 3 2 If i assumed that 4 -3 5 -4 6 -2 The fundemetal component should be the same but other coefficient will be changed?

i didnt really understand what you said about the polynomilas, can you explain more please, if you don't mind. about duplication ... he can't do that because there is no half wave symmetry ( the real function is actually longer than what i wrote , i just tried to give a simplified example)...

What he basically wants to do is get the graph of the integral of the function where C=0 But when he used numerical integration methods (because he doesn't have the function he has points) he got the right graph but there is a dc offset , he wants to remove it to get the right graph

Doesnt fft require an integer number of cycles sampled? As for the filters, he tried on MATLAB to multiply by this transfer function ( (1-z)/(1-0.95z)) he read somewhere online that this T.F blocks dc , then he set the simulation to end after half the period and it didnt work.

Sorry for the late reply, i am asking for a friend so i had to get back to him, he said " he has a half cycle of the function not just the x or the 4x , he can't get a full cycle because the period is very long he doesn't have time to get a full cycle ( it's some kind of mechanical application...

Yes it would work but i can't because i don't have the full cycle so i can't get its average

I wanted to remove the dc component from a signal but i can't use the average method because i have only a half cycle sampled not a full cycle . Is there any algorithm or method that can remove the dc component using only a half cycle? (The signal is sin(x)+2*sin (2x) +3*cos (3x)+4*cos (4x) +5...

I still don't know why we put the brush at the point where the current is 0, we need max output so we should put it where the emf is max right?
