+% FIR filter design with Python and SciPy
+% Matti Pastell
+% 15th April 2013
+
+# Introduction
+
+This an example of a script that can be published using
+[Pweave](http://mpastell.com/pweave). The script can be executed
+normally using Python or published to HTML with Pweave
+Text is written in markdown in lines starting with "`#'` " and code
+is executed and results are included in the published document.
+The concept is similar to
+publishing documents with [MATLAB](http://mathworks.com) or using
+stitch with [Knitr](http://http://yihui.name/knitr/demo/stitch/).
+
+Notice that you don't need to define chunk options (see
+[Pweave docs](http://mpastell.com/pweave/usage.html#code-chunk-options)
+),
+but you do need one line of whitespace between text and code.
+If you want to define options you can do it on using a line starting with
+`#+`. just before code e.g. `#+ term=True, caption='Fancy plots.'`.
+If you're viewing the HTML version have a look at the
+[source](FIR_design.py) to see the markup.
+
+The code and text below comes mostly
+from my blog post [FIR design with SciPy](http://mpastell.com/2010/01/18/fir-with-scipy/),
+but I've updated it to reflect new features in SciPy.
+
+# 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.
+
+## Functions for frequency, phase, impulse and step response
+
+Let's first define functions to plot filter
+properties.
+
+
+<<>>=
+from pylab import *
+import scipy.signal as signal
+
+#Plot frequency and phase response
+def mfreqz(b,a=1):
+ w,h = signal.freqz(b,a)
+ h_dB = 20 * log10 (abs(h))
+ subplot(211)
+ plot(w/max(w),h_dB)
+ ylim(-150, 5)
+ ylabel('Magnitude (db)')
+ xlabel(r'Normalized Frequency (x$\pi$rad/sample)')
+ title(r'Frequency response')
+ subplot(212)
+ h_Phase = unwrap(arctan2(imag(h),real(h)))
+ plot(w/max(w),h_Phase)
+ ylabel('Phase (radians)')
+ xlabel(r'Normalized Frequency (x$\pi$rad/sample)')
+ title(r'Phase response')
+ subplots_adjust(hspace=0.5)
+
+#Plot step and impulse response
+def impz(b,a=1):
+ l = len(b)
+ impulse = repeat(0.,l); impulse[0] =1.
+ x = arange(0,l)
+ response = signal.lfilter(b,a,impulse)
+ subplot(211)
+ stem(x, response)
+ ylabel('Amplitude')
+ xlabel(r'n (samples)')
+ title(r'Impulse response')
+ subplot(212)
+ step = cumsum(response)
+ stem(x, step)
+ ylabel('Amplitude')
+ xlabel(r'n (samples)')
+ title(r'Step response')
+ subplots_adjust(hspace=0.5)
+@
+
+## Lowpass FIR filter
+
+Designing a lowpass FIR filter is very simple to do with SciPy, all you
+need to do is to define the window length, cut off frequency and the
+window.
+
+The Hamming window is defined as:
+$w(n) = \alpha - \beta\cos\frac{2\pi n}{N-1}$, where $\alpha=0.54$ and $\beta=0.46$
+
+The next code chunk is executed in term mode, see the [Python script](FIR_design.py) for syntax.
+Notice also that Pweave can now catch multiple figures/code chunk.
+
+
+<<term=True>>=
+n = 61
+a = signal.firwin(n, cutoff = 0.3, window = "hamming")
+#Frequency and phase response
+mfreqz(a)
+show()
+#Impulse and step response
+figure(2)
+impz(a)
+show()
+@
+
+## Highpass FIR Filter
+
+Let's define a highpass FIR filter, if you compare to original blog
+post you'll notice that it has become easier since 2009. You don't
+need to do ' spectral inversion "manually" anymore!
+
+
+<<>>=
+n = 101
+a = signal.firwin(n, cutoff = 0.3, window = "hanning", pass_zero=False)
+mfreqz(a)
+show()
+@
+
+## Bandpass FIR filter
+
+Notice that the plot has a caption defined in code chunk options.
+
+
+<<caption="Bandpass FIR filter.">>=
+n = 1001
+a = signal.firwin(n, cutoff = [0.2, 0.5], window = 'blackmanharris', pass_zero = False)
+mfreqz(a)
+show()
+@

+The Hamming window is defined as:

+\section{Introduction}
+
+This an example of a document that can be published using
+\href{http://mpastell.com/pweave}{Pweave}. Text is written
+using \LaTeX{} and code between \texttt{<<>>} and \texttt{@} is executed
+and results are included in the resulting document.
+
+You can define various options for code chunks to control code
+execution and formatting (see
+\href{http://mpastell.com/pweave/usage.html\#code-chunk-options}{Pweave
+docs}).
+
+\section{FIR Filter Design}
+
+We'll implement lowpass, highpass and ' bandpass FIR filters. If you
+want to read more about DSP I highly recommend
+\href{http://www.dspguide.com/}{The Scientist and Engineer's Guide to
+Digital Signal Processing} which is freely available online.
+
+\subsection{Functions for frequency, phase, impulse and step response}
+
+Let's first define functions to plot filter properties.
+
+
+<<>>=
+from pylab import *
+import scipy.signal as signal
+
+#Plot frequency and phase response
+def mfreqz(b,a=1):
+ w,h = signal.freqz(b,a)
+ h_dB = 20 * log10 (abs(h))
+ subplot(211)
+ plot(w/max(w),h_dB)
+ ylim(-150, 5)
+ ylabel('Magnitude (db)')
+ xlabel(r'Normalized Frequency (x$\pi$rad/sample)')
+ title(r'Frequency response')
+ subplot(212)
+ h_Phase = unwrap(arctan2(imag(h),real(h)))
+ plot(w/max(w),h_Phase)
+ ylabel('Phase (radians)')
+ xlabel(r'Normalized Frequency (x$\pi$rad/sample)')
+ title(r'Phase response')
+ subplots_adjust(hspace=0.5)
+
+#Plot step and impulse response
+def impz(b,a=1):
+ l = len(b)
+ impulse = repeat(0.,l); impulse[0] =1.
+ x = arange(0,l)
+ response = signal.lfilter(b,a,impulse)
+ subplot(211)
+ stem(x, response)
+ ylabel('Amplitude')
+ xlabel(r'n (samples)')
+ title(r'Impulse response')
+ subplot(212)
+ step = cumsum(response)
+ stem(x, step)
+ ylabel('Amplitude')
+ xlabel(r'n (samples)')
+ title(r'Step response')
+ subplots_adjust(hspace=0.5)

+
+\subsection{Lowpass FIR filter}
+
+Designing a lowpass FIR filter is very simple to do with SciPy, all you
+need to do is to define the window length, cut off frequency and the
+window.
+
+The Hamming window is defined as:
+$w(n) = \alpha - \beta\cos\frac{2\pi n}{N-1}$, where $\alpha=0.54$ and
+$\beta=0.46$
+
+The next code chunk is executed in term mode, see the source document
+for syntax. Notice also that Pweave can now catch multiple
+figures/code chunk.
+
+<<term=True>>=
+n = 61
+a = signal.firwin(n, cutoff = 0.3, window = "hamming")
+#Frequency and phase response
+mfreqz(a)
+show()
+#Impulse and step response
+figure(2)
+impz(a)
+show()
+@
+
+\subsection{Highpass FIR Filter}
+
+Let's define a highpass FIR filter:
+
+<<>>=
+n = 101
+a = signal.firwin(n, cutoff = 0.3, window = "hanning", pass_zero=False)
+mfreqz(a)
+show()
+@
+
+\subsection{Bandpass FIR filter}
+
+Notice that the plot has a caption defined in code chunk options.
+
+
+<<caption="Bandpass FIR filter.">>=
+n = 1001
+a = signal.firwin(n, cutoff = [0.2, 0.5], window = 'blackmanharris', pass_zero = False)
+mfreqz(a)
+show()
+@
+
