Alex's Assignment

==Alex's Fourier Project==
I chose to do my LNA project on a spring mass and dampener system such as what you would find on an automobile. As shown on the picture we have a mass (M), spring (K), and dampener (D).

[[Image:LNAHW-8.jpg|thumb|500px|right]]

==General Equations==
The first thing I need to do is write down the general equations for the Fourier Series:

<math>\begin{align}
x(t) &= x(t+T) = a_0 + \sum_{n=1}^\infty a_n \cos(n\omega_0t) + b_n \sin(n\omega_0t)\\
\omega_0 &= 2\pi f_0\\
a_0 &= \frac{1}{T}\int_0^T f(t)\, dt\\
a_n &= \frac{2}{T}\int_0^T f(t)\cos(n\omega_0t)\, dt\\
b_n &= \frac{2}{T}\int_0^T f(t)\sin(n\omega_0t)\, dt\\

\end{align}
</math>

If odd function, <math>a_n = 0</math>

If even function, <math>b_n = 0</math>

==Equations==

Now that we have the basic equations for a Fourier Series we can begin to calculate for the spring dampener system.
knowing that as the vehicle travels down a rough road it creates a displacement x we can equate the formula for the system.
The forces apposing the displacement are:

The mass of the vehicle for one tire <math>\frac{1}{4}M</math>

The spring constant <math>Kx</math>

And the Dampening of the shock <math>Du</math>

Plugging in the forces into an Ordinary Differential Equation we get:

<math>Mu'+Du+Kx=0</math>

You can change the colors of the Plots by entering a color command before choosing the line style of the plot.
plot(time, Volts, 'r-')

there are many different colors:
"r" = red
"g" = green
"b" = blue
"m" = Magenta
"c" = cyan
"w" = white
