Create a patch from a chirp signal.

Simply uses scipy.signal.chirp under the hood.

Parameters

Parameter	Description
sample_rate	The sample rate in Hz.
time_min	The start time in the metadata.
channel_count	The number of distance channels to include.
duration	The duration, in seconds, of the signal.
f0	The frequency of the chirp at the start of the signal.
f1	The frequency of the chirp at the end of the signal.
t1	The time (relative from signal start) corresponding to f1. If None, use the end of the signal.
method	The kind of the frequency sweep. See scipy.signal.chirp for more details.
phi	Phase offset in degrees.
**kwargs	Passed directly to scipy.signal.chirp.
