Homework Statement
Design serial transmitter circuit take 8-bit word in parallel as input, when an input control signal (SEND) goes high, and serially outputs the word (i.e., one bit during each clock cycle) to a single transmission line. Transmission of a word begins with the least...

The Attempt at a Solution
So I was looking at an example and I wanted to know how this energy band diagram was drawn from the picture. As the x increased the doping level decreased, but how can I know if it will...
I was going to use the formatting but I don't think there's any equations involved with this(at least that I've used in digital logic), and the question itself is a picture
I understand what a state transition table is and how it works, what I don't know is how they created the table from just...
So I was reading my book and I came across a table, I don't understand how they converted the problem into a table.
They're designing a sequential logic machine and it looks like they made a K map of something, but I don't know what they used. Can anyone explain how the book did this...
Am I suppose to treat it as two different Laplace transforms combined? Not sure how that would work but I know the two individual formulas below
2/((s+4)^2)
1/s^n = t^n-1/(n-1)! = x*2
and
1/(s-a) = e^-4x
2*e^(-4*x) is what I get, I don't know where the other x came from.
Well I mean I know it's because it's squared, I just don't see how my laplace transform formula is giving me that
Homework Statement
So I know 1/(s-a)=e^(a1), but why is say, 2/((s+4)^2) equal to 2xe^-4x? Do I just simply add an X if the numeration is a constant other than 1?
Homework Statement
A sample of Si, in which 0<=x<=(25*10^-4), electron concentration is n(x)=5*10^16 cm^-3) * exp(-x^3/2*10^-8), temperature is 300k and electron mobility is 1300 cm^2/V*s. The electron current through the Si has both drift and diffusion components and total electron current...
x^2=((1.04*10^19*6*10^18)*(400/300)^3exp(-.66/(400*8.62*10^-5))
=8.50*10^14, does this look more correct? I fixed errors in my last post
My calculated ni for 300k is off by a bit though... it's suppose to be 2.4*10^13 but I calculated 2.2*10^13 using the same method above. Did I make a mistake?
