Instantaneous Phase Calculator

Posted by Dinesh on

Instantaneous phase and instantaneous frequency are important concepts in signal processing that occur in the context of the representation and analysis of time-varying functions.

Instantaneous Phase Calculation

Formula:

Φ(t) = arg[s(t)]

where,
s(t) - real valued function
arg - is the argument function
Φ(t) - instantaneous frequency or phase
