Magnitude and Phase Angle for Nyquist Plots
Homework Statement
The assignment is to draw a Nyquist Plot of a certain transfer function. The problem is that I can't figure out how they got the angle for the plot.
G(s) = \frac{k(s+2)}{(s+1)(s-3)}

Well the module "freq_divider" is an instance in my top level file. Maybe I defined it wrong or something, because in my simulations, the signals don't do anything. Here is the new frequency divider and top level modules (I tried cleaning up the top level as much as possible, because most of the...
Yup. Here is the code I wrote last summer:
module freq_divider(
clk, //Clock 50 MHz
reset_n, //Active low reset
divided_frequency, //Divided frequency
new_freq,
current_q //Current value
);
input clk;
input reset_n;
output divided_frequency;
output [11:0] current_q...
Thanks everyone for the replies.
negitron - it makes sense to me, but I don't know how to implement it
Fenn - I'm trying to use the FPGA on the development board, but thank you anyway, I might use that for some other project.
berkeman - I've looked at a bunch of Verilog tutorials, but I can't...
Hey guys,
I'm using the Altera Cyclone II FPGA Development Board, with the goal of controlling a relay. I need to divide 24MHz to get 1kHz, but I don't know how to write the code for it. I know one way to divide it, would be to have a 10bit counter, which will allow me to divide it by 1k...
I'm trying to figure out how to convert from decimal to binary. I've read a few explanations but I still don't understand. Could someone please help?
The method I've read about invloved dividing the number you want to convert, by 2 each time, and looking at the remainder.
Homework Statement
An electron is confined in a box where a = 60nm, b = 20nm, c = 35nm. For each of the first four quantum levels above the ground state give:
a) The quantum numbers
b) The speed of an electron trapped at that level
c) The wavelength of light needed to excite an electron...
Actually yes, and I'm stuck on that too.
Also, I thought I figured out how to finish the first part, but it's not working out.
Here's what I'm getting:
\oint \bold{E} \cdot d\bold{l} = \oint_0^1 xy dx + \oint_0^1 -x^2-2y^2 dy + \oint_c^a \bold{E}_{ca} \cdot d\bold{l}
but I don't know...
Thanks for the quick reply. I have 2 questions:
1) Shouldn't the integral from a to b, be \oint_a^b \bold{E}_{ab} \cdot \hat x d\bold{l} since ab is horizontal?
2) I'm not sure what to put for \bold{E}_{ab}. Should it be the component that acts only in the direction of ab, in other words...
Homework Statement
For the vector field \bold{E} = \bold{ \hat x} (xy) - \bold{ \hat y} (x^2 + 2y^2), calculate the following:
\oint \bold{E} \cdot d\bold{l} around the triangular contour shown.
I don't have a scanner at the moment so I will explain the drawing. The picture is a right...

I'm taking a metrials class, and there are 2 questions I'm not sure how to do. I would see the professor first, but he refuses helping students until the assignments is submitted.
