WebA chirp signal is a burst of waves that can be synthesized (referred to here as controlled chirps) or otherwise created and processed. However, chirps are frequently used … WebMay 10, 2024 · however, when the source causes the signal to change in amplitude and no freq changes are present, it is when my problem starts. If one would imagine a spectrogram rapresentation of this: the signal would be a constant line, with some fast peaks occurring here and there (chirps). Using the medfreq function these are nicely detected.
