WebSep 2, 2024 · Phase (of chirp): quadratic. Must be careful with what's meant by "phase"; the instantaneous, i.e. the complete input, ϕ ( t): cos ( ϕ ( t)). The instantaneous frequency of cos ( t 2) isn't t, but t / 2; see here. Phase (of freq response): parabolic, with half-parabolas symmetric about and adjacent to the spike at f max / 2.
