Assignment II - makeup and addendum

As a quick reminder, the frequency has to be integrated to get the phase.
The command for that in Matlab is cumsum.
For our next class correct / complete the chirp assignment. Design your
initial and final frequency so that it starts below Nyquist and goes over
it (if you want, it can continue rising beyond sampling frequency as well).
Describe what you hear. See this in specgram. Explain.
Note: in order to keep the aliasing effect in audible range, use Nyquist
around 2KHz.
