Command line arguments This is a short excerpt from
next week's first lecture that you will need to solve
the Fibonacci Numbers problem.
In the lecture on sampling, convolution, and Fourier transforms, there is a mistake in the convolution and signal recovery illustration starting at 9:08. I left out a factor of π in the argument of the sine function and the denominator of g(τ). You may wonder how the signal recovery worked so well even though I did this. It turns out that although most people define the sinc function as sin(x)/x, some use a normalized sinc function, which is sin(πx)/(πx). The NumPy library happens to use the normalized version, so when I called np.sinc(τ/T), I got sin(πτ/T)/(πτ/T), which is the correct function. It is easier to use np.sinc() than np.sin(x)/x, since np.sinc() will prevent division by zero if x = 0. You can see the corrected illustration by running this program.
