-This an example of a julia script that can be published using
-[Weave](http://mpastell.github.io/Weave.jl/latest/usage/).
-The script can be executed normally using Julia
-or published to HTML or pdf with Weave.
-Text is written in markdown in lines starting with "`#'` " and code
-is executed and results are included in the published document.
-
-Notice that you don't need to define chunk options, but you can using
-`#+`. just before code e.g. `#+ term=True, caption='Fancy plots.'`.
-If you're viewing the published version have a look at the
-[source](FIR_design.jl) to see the markup.

-## Design Lowpass FIR filter
-
-Designing a lowpass FIR filter is very simple to do with DSP.jl, all you
-need to do is to define the window length, cut off frequency and the
-window. We will define a lowpass filter with cut off frequency at 5Hz for a signal
-sampled at 20 Hz.
-We will use the Hamming window, which is defined as:
-$w(n) = \alpha - \beta\cos\frac{2\pi n}{N-1}$, where $\alpha=0.54$ and $\beta=0.46$
