Beat Frequency Formula

Formula

f_beat = |f₁ - f₂|

Where:

  • • f_beat = beat frequency (Hz)
  • • f₁ = first frequency (Hz)
  • • f₂ = second frequency (Hz)

The beat frequency is the absolute difference between the two frequencies.

Applications

  • • Tuning musical instruments
  • • Doppler effect measurements
  • • Frequency modulation
  • • Sound wave interference
  • • Radio frequency mixing
