"WebJun 26, 2012 · A smooth sinusoid requires continuous phase. Phase is the integral of frequency, so if you have a linear function for frequency (i.e. a constant-rate increase from f1 to f2), then phase will be a quadratic function of time. You can figure out the maths with pen and paper, or I can tell you that the resulting waveform is called a linear chirp. " - Chirp function
