Video: GNU Radio Companion: Acoustic Beats

Filed under: technology,video — Didier Stevens @ 13:39

In this video, I use GNU Radio Companion (without SDR) to illustrate the acoustic beat phenomenon.

I mention a 400Hz dial tone in this video, but this will vary by country.

  2. Excellent exposition Didier! Thank you. It was interesting to see that the waveform for beats is the same as 100% modulation for an amplitude modulated radio wave.
