# Introduction
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.
# FIR Filter Design
We'll implement lowpass, highpass and ' bandpass FIR filters. If
you want to read more about DSP I highly recommend [The Scientist
and Engineer's Guide to Digital Signal
Processing](http://www.dspguide.com/) which is freely available
online.

## 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 $\beta=0.46$
