-Before you begin, do a ''​git pull''​ from the course repository. Also, to reproduce the figures shown here, change the default font size (''​set(0,'​DefaultAxesFontSize',​18)''​ -- a good place to put this is in your path shortcut). +Let's start with an example that illustrates what can go wrong if you are not aware of some basic sampling theory ideas. To do so, we will first construct a 10Hz signal, sampled at 1000Hz ​(i.e. we are taking 1000 measurements per second). Recalling that the frequency //f// of a sine wave is given by $y = sin(2 \pi f t)$:
