I have found a spec analyzer that is rated from 100Hz to 9MHz (might be more on the higher side, my memory is poor) Which is a suitable range for the measurements i am looking to do.
How would i measure the Current Noise Density using a spec analyzer? Is there a simple operation?
By the way, i...
What kind of info are you looking for? I am a layman when it come's to this topic. The only thing that is special about this power supply is that it was made to power our system specifically and was constructed to have low noise. The configuration of the power supply is it can be powered by...
I have a power source that is supposed to be low noise, and i want to verify that the data the company sent me is indeed accurate. In order to do this, i want to reproduce their graph showing current noise density (nA/root(Hz)) on the Y axis, and Hz on the X axis. I am an undergraduate physics...
To be honest i can do the problems but the cauchy integral theorem still perplexes me. I understand the integral fails if there is a "hole" within the integral, and equals 0 everywhere else. So i guess what I am really trying to integrate is the pole? So the entire point is to find the integral...
Okay so an integral is analytic if it satisfied the cauchy reimann equations. Basically what i know is if an equation satisfies the cauchy reimann equations, all is good and it can be worked with. I need to solve the second order cauchy reimann equation in order to prove a function is harmonic...
I know, i am struggling in this class and I am trying to keep up with it. I am going to re-read the chapter in order to understand the cauchy integral theorem but to be honest I am pretty poor at learning math out of books. I am best at visualizing problems which is particularly difficult in...
Okay so third times a charm, i figured out that it is not f^(m-1), but f with derivatives equal to m-1.
So since my m=1 for this, i do not have to take a derivative but only evaluate it at 3/2 over !0.
so my answer is pi * i * 3/2 * e^(3/2)
Okay so i have looked abck and tried to understand the derivation again, and have realized it comes as a consquence of the equation integral of f(z)/(z-z0)^m dz is equal to 2pi*i f^(m-1) (z0) / (m-1)!
(if anyone finds my notation to be confusing or sloppy, i can rewrite it. also is there a...

Homework Equations
I am confused as to a step in my solution, but i believe a relevant equation is if i am integrating over a circle and the function is analytic...
I would suggest you don't, i was the same way and wanted to take advanced courses earlier to jump ahead and really get going with the real "meat" of physics work, and if your looking to go on to grad school later i think its best to slow it down, keep doing the normal stuff and not delve into...
I rechecked the normalization coeffecient, and substituted in my expressions for E1
and E2, (Hbarω and 4hbarω respectively) t get an expression for ψ(x,t).
Now the directions said to use eulers formula to simplify and elminate exponentials... soo...

You can see I am quite new (and perhaps not the best) at this? so i am reading and figuring this out as i go and i found that
ψ(x,t) = ψ(x)*e-iEt/hbar
Since i was given En, i can substitute that in for E in the above equation.
yielding:
ψ(x,0) = 1/4[ψ1(x)e-iE1t/hbar +...
Okay, so now knowing that A=1/4 i return to my equations...
ψ(x,0) = A[ψ1(x) + ψ2(x)]
and I am looking to find Find ψ(x,t).
In order to do this i need to know change my equations for ψ so that they are related to t, time. I am given ω (angular frequency) which i know is related to t...
(wrote this before i saw the above response)
Maybe i can't evaluate it from 0 to L?
Should I be evaluating it from negative infinity to positive infinity (i could then double the integral, and evaluate from 0 to infinity because Sin^2 is a even function)
The bad part is we went over this part...
