torchsig.signals.builders.chirp.chirp(f0: float, f1: float, samples_per_symbol: int, phi: float = 0) → ndarray

Creates chirp symbol.

Parameters:

• f0 (float) – Starting frequency for the chirp.

• f1 (float) – Ending frequency for the chirp.

• samples_per_symbol (int) – Number of samples for the chirp symbol

• phi (float, optional) – Starting phase in radians. Defaults to 0.

Returns:

Chirp waveform.

Return type:

np.ndarray
