The Hilbert transform has many practical applications. These include vibration analysis and amplitude modulation in communication systems

This application compute the envelope and instantaneous frequency of a signal using the Hilbert transform.
  • The signal envelope is the magnitude of the Hilbert transform
  • The instantaneous frequency is the derivative (wrt time) of the phase angle of the Hilbert transform (only for single-component signals)
The magnitude of the analytic signal captures the slowly varying features of the signal, while the phase contains the high-frequency information.
