| Unit 30 | Generating a Synthetic Sine Wave |
It’s time to impress our non-numpy friends and do something that data scientists normally don’t do: generate a synthetic sine wave, a periodic signal that we could have captured using a cheap, imperfect, and noisy instrument with a limited range. The actual provenance of the signal and the nature of the instrument are not really important. Perhaps it was a voltmeter that you hooked into an electrical outlet, an outdoor digital thermometer that you left on your lawn on Sunday night and collected only on Friday, or even a stock market price ticker. (By the way, you can use synthetic periodic signals not just to impress friends, but also to test new digital signal processing algorithms.)
