WebOct 3, 2024 · The general expression for the basic chirp, ignoring the amplitude, phase and frequency, is written as x(t) = ej ( πμt2 + 2πft + θ) The factor π is actually 2π scaled by 1 / 2. This is included to normalize the chirp rate as the slope of the instantaneous frequency which is defined as the derivative of the argument.
