Signals 101

Signals and systems in under a minute each: periodicity, harmonics, sampling, spectra. Every waveform on screen is computed, not sketched.

  1. 01Add two sine waves. It never repeats.✓ published
  2. 02Your computer thinks 11 Hz is 1 Hz
  3. 03Sample at exactly Nyquist and this sine wave vanishes. Why?
  4. 04One sine wave carries 81% of a square wave. Guess before you watch.
  5. 05A square wave has no 2nd harmonic. It's not because it's odd.
  6. 06This signal has no 4th harmonic. Guess why before you watch.

Watch them on the Electronics 101 YouTube channel. Episodes without a tick are finished and queued for release.
